Performance Problems

Painfully slow with multi-second page loads

Users describe Jira as 'bloated and ridden with technical debt.' Creating a ticket can take 10 seconds to open. The software runs 'embarrassingly slow' with 10-20 second hangs when navigating. Users report 'you can make yourself a cup of tea while waiting for all the issues to load.' Page refresh downloads batch.js files that can be 26MB causing huge lag.

Third-party plugins cause thread exhaustion

Atlassian documentation acknowledges that 'performance may slowly deteriorate due to stuck threads and thread pool exhaustion caused by third-party apps.' The plugin ecosystem that makes Jira powerful also makes it unstable. Batch.js files from plugins can reach 26MB, causing massive lag.

New lead page update caused productivity drop

After Close introduced a new lead-page design, users reported significant productivity drops. Complaints include: crucial functions missing, bugs appearing frequently, high latency/increased loading time, no overview in dropdowns, and difficulty in general use. Support responded with templates instead of taking problems seriously.

Call quality issues with slowness and voice distortion

Users experience call issues including slowness, voice distortion, and missing call time details. The power dialer sometimes won't allow sending messages to certain leads, displaying errors that tell users to 'just contact Close support.' Performance during calls has been criticized as slow.

Email sync problems link messages to wrong contacts

Reviewers report persistent sync problems with emails occasionally linking to incorrect opportunities or failing to sync entirely. The Gmail plugin is described as inefficient, with the system lagging when running multiple email accounts in one browser.

System slows down significantly with larger databases

With a larger database of leads, Copper sometimes bogs down and loads slowly. Users report persistent bugs, slow loading, and unresolved technical problems that disrupt workflow and cause frustration.

Database performance degrades at 5,000+ records

Users report significant performance degradation once databases exceed 5,000 records. Loading times increase from instant to 3-5 seconds per page. Filtering, sorting, and searching large datasets feels sluggish compared to dedicated database tools like Airtable. The issue is particularly severe on mobile devices or slow internet connections due to Notion's client-side architecture that loads entire pages.

Desktop app consumes excessive RAM - up to 4GB per workspace

Slack's memory footprint increases as users sign into more teams, as each team runs in its own webview. Running the app continuously can result in it devouring nearly 4GB of RAM. Users report that if you care about battery life or CPU/memory availability, you shouldn't use Slack desktop with more than one or two accounts. Resource usage increases linearly as you add more accounts.

Desktop app and web interface become slow with many tasks

Users on Asana Forum report the desktop app becoming 'unbearably slow' and the web interface lagging 'to the point of slow load screens and inability to type.' Tasks sometimes show empty screens for 10+ seconds before loading. Recent outages in January 2026 affected non-US users for ~50 minutes.

Large boards become extremely slow

Users consistently report severe performance issues with large boards. A CRM user with 60-70 columns reported item cards taking 25+ seconds to load. Another user said dashboards pulling from 12-15 boards take 40+ seconds. The Monday.com community forum has multiple threads about boards consuming 1.5-1.6GB of memory and freezing.

Platform is extremely slow and buggy

Users consistently report ClickUp being 'practically unusable — slow, extremely slow.' One user described it as 'the worst tool currently on the market' due to performance. On Safari it 'basically doesn't work at all.' Screen updates don't show for some users while others see them, causing sync issues.

Slow performance and frequent crashes

The app suffers from slow loading and lag, particularly on mobile. The web app takes 30 seconds to a minute to load before you can do anything, with upgrade pop-ups appearing every time. Users report V10 getting slower on loading notes and searching, with frequent crashes especially when handling large amounts of data.

Load times can take hours, graph view slows down

There are occasions when load times can take hours. The graph view gets slow particularly when users have many notes and the graph is large. Offline graph loading causes browser freezes and high CPU usage in some browsers.

Syncing slow and inconsistent for large files

While Dropbox uses efficient block-level syncing, users still report slow and inconsistent synchronization with large files. The system can freeze or become unresponsive. Some users experience files not syncing at all or sync conflicts creating duplicate files.

Painfully slow sync speeds frustrate users

OneDrive syncing is notoriously slow, especially when tracking many files. Users report the client makes Windows Explorer sluggish and unresponsive. Large files and SharePoint sites exacerbate the problem. Some users wait hours for routine syncs to complete. Microsoft's advice is essentially 'have fewer files.'

Painfully slow with large files - no block-level sync

Box doesn't support block-level syncing, meaning entire files must re-upload for small changes. Large media files sync slowly and become resource-intensive. Users working with video, design files, or large datasets face significant productivity issues.

High CPU usage causes system lag and freezing

Zoom requires nearly 4GB RAM and can strain system resources, causing lag, audio/video distortion, or complete freezing. Users with older machines or running other applications report their entire computer becoming sluggish during Zoom calls.

Extremely high RAM usage even when idle

Teams consistently uses 1GB+ RAM even when idle, spiking higher during meetings. Microsoft admitted in November 2025 that Teams 'eats RAM on Windows doing nothing.' Users report system slowdowns, freezes, and lag. A fix is promised for January-February 2026 but core architecture issues persist.

Poor audio quality compared to competitors

Multiple forum discussions describe Webex audio as 'the worst of comparable services' - like 'listening to the Charlie Brown teacher underwater during a storm.' Users report choppiness, dropped calls, high latency causing people to talk over each other, and audio loss during calls.

Audio and video sync issues (Loom lag)

Users frequently experience 'Loom lag' where audio and video fall out of sync, making videos hard to watch and understand. Audio cuts out, becomes choppy, or microphone issues persist. Camera feed sometimes disappears during recording.

Performance issues and laggy interface

GitHub Issue #23104: 'Local dev crazy slow' - page load 10-12 seconds on high-end machines, goal to reduce by 80%. Trustpilot 1-star: 'everything is laggy'. Self-hosted instances particularly affected during traffic spikes. Cold starts historically up to 30 seconds.

System performance issues - hanging and slow loads

Users report the platform 'hanging' or failing to load content. Specific issues include emails not sending or taking too long to save, and the repeated need to log out, clear cache, and restart browser to troubleshoot.

Slow loading times and lag issues

Users face slow loading issues with Zoho CRM, leading to frustration and complicating daily workflows. Performance particularly degrades when working with large amounts of data or generating complex reports. Some users notice occasional lag that impacts productivity during peak usage times.

System slowness and sync delays

Users report instances where the system gets stuck or is slow to sync, delaying the appearance of new deals or contacts in searches. This hinders the process of linking emails or creating new deals. The interface bounces to the bottom or top unexpectedly when entering notes, disrupting workflow.

Bugs and glitches persist especially in bulk editing

Users experience bugs and glitches particularly impacting bulk editing functionality. One customer paying $649/month reported still being unable to pull basic revenue KPIs because project budgets don't roll up correctly.

Platform runs slow with large contact lists

The platform can be slow when working with large contact lists. Users have difficulty accessing key data in their accounts, with endless discussions with customer service and development teams to resolve issues.

Segment loading and template editor painfully slow

Segment loading can be painfully slow compared to lighter tools. The template editor text box is almost dysfunctional due to auto-saving, taking hours to edit templates. Occasional glitches like overlapping fields when exporting interrupt workflows.

Platform slowdowns when handling large datasets

Users report slowdowns when working with large contact lists or complex automations. Performance degrades as data grows. Some features become nearly unusable with big datasets.

Platform slow when handling larger contact lists

Users experience slow performance when working with larger contact lists. Platform responsiveness degrades as data grows. This impacts workflow efficiency for growing businesses.

Slow site speed affecting SEO and conversions

BigCommerce websites tend to be slower compared to other ecommerce platforms, negatively impacting SEO and bounce rates. Users have no control over hosting configurations since BigCommerce handles all hosting. The more apps installed, the slower the site becomes, with each app adding code that loads on every page view.

Slow page speed affecting SEO and user experience

Squarespace sites consistently score poorly on Google PageSpeed tests. Users cannot control hosting settings, compress images below 100KB reliably, or use next-gen formats like WebP. Site speed is a Google ranking factor, making this a significant SEO handicap that's nearly impossible to fix.

Slow page loading speeds hurt user experience

Wix sites are frequently criticized for slow loading times due to heavy JavaScript code, shared hosting environment, and the platform's architecture. Google PageSpeed scores are often poor, affecting both user experience and SEO rankings. Limited optimization options available to users.

Designer editor painfully slow and crashes

Users report the Designer is painfully slow even on high-end machines. The ecommerce tool crashes when managing products. Major outages in 2025 left users unable to access the platform for hours while the status page showed 'Operational'. Publishing failures and Designer not loading are common complaints.

Editor becomes sluggish on complex sites

The Framer editor slows down significantly on sites with many pages, complex animations, or large image assets. Users on lower-end machines experience freezing and lag. Browser memory consumption can exceed 4GB on complex projects.

Sites slow down with plugins and complexity

WordPress sites commonly suffer from slow loading times, especially with many plugins, heavy themes, and complex configurations. Performance optimization requires significant effort - caching plugins, image optimization, CDNs. Out of the box, WordPress is notably slower than Ghost, Webflow, or static sites.
