Same. JIRA is just slow, even in basic configuration. Which is always annoying me because JIRA is 99% read-only. They could generate most of the pages and cache them until anything changes. Even pre-generate then on change. But every time you view an issue, it takes multiple seconds again.

This is a common 'but sometimes' issue in software engineering.

Caching works for 99.9% of cases, 'but sometimes', I click on an issue and it was just updated just before my page rendered.

I've setup Jira (on premise) at my workplace myself. Runs behind an nginx reverse proxy and it is indeed pretty fast!

We don't use much stuff and it's a bit older version 7.8, but I cannot complain so far.

Installed a plain Jira software instance on Docker, that wasn’t terribly slow.
