Description

NOTE: This bug report is for JIRA Server. Using JIRA Cloud? See the corresponding bug report.

Summary

We're seeing an increasing number of issues where customers are reporting initial page load times in excess of 10-15 seconds, and sometimes more.

Cause

When accessing a page within JIRA, a set of batch.js and batch.css files are provided that contain the batched Javascript and CSS resources for the page. Upon first load of a page this cache is created (if it does not already exist on the server), and is then stored for future loads of the page. This cache is a server-side cache and is separate from the client-side cache (ie the cached batch.js and batch.css files in the browser). The creation of the cache can take some time - 10 to 15 seconds - so on first load of a page it will take some time for the page to load.

On first load of any page in JIRA it does download quite a lot of content, which is then cached in the browser, so it is expected that the first page-load will be longer than any subsequent page loads. This is exacerbated when the cache is being recreated as it adds even more time onto that page load.

The cache is created on a language/locale basis, so for example if users access a page in English it will be generated, and other users access pages in Russian it will be generated again. The cache is invalidated when there are Look & Feel changes, or plugin changes occur. This means if these changes occur the cache will need to be recreated and will cause page load times to increase until the cache is created and stored server-side. If there are users with a variety of different languages using the server it will mean the cache is recreated multiple times.

In certain cases where multiple concurrent requests take place they can end up all running the batch generation simultaneously, leading to the CPU spiking and the instance potentially becoming unresponsive while all the requests are processed.

Once a type of page has been visited per user (e.g. the dashboard, a JIRA issue or a project page) the batch.css will be cached for that type of page until the next restart or plugin change. So the first time you view one of these pages the performance will be slow, but it will improve significantly on each subsequent visit.

Steps to reproduce

Go to any JIRA instance - this can be easily replicated with a jira-dev instance
Disable or enable a plugin
Load the dashboard

Looking at the Network tab of developer tools, you'll see that there's a long delay in loading those batch files.

Workaround

Schedule plugin changes during off-peak periods, and then visit a page in JIRA to ensure the cache is recreated during that off-peak period.

Note: It is always best practice to schedule plugin installations and upgrades in off-peak periods or during maintenance windows. For JIRA Download customers it is also recommended to perform major plugin changes on a staging instance before it is done on a live environment.

Diagnosis

For one of the ways of identifying this problem, this will show us the number of threads waiting to process LESS compilation. A higher number over a series of thread dumps can be considered bad.

The below is being executed in a folder with a significant number of thread dumps labelled jstack that were taken over a series of days.

$ grep -B1 "com.atlassian.plugin.cache.filecache.impl.CachedFile.stream" jstack* |grep "waiting to lock" |awk '{print $1}' | sort |uniq -c
  31 jstack.13007.110759.851358689-
  58 jstack.13007.110810.528822009-
  54 jstack.13007.110821.172461523-
  42 jstack.4440.threadHigh.103649.939600529-
  44 jstack.4440.threadHigh.103701.620551473-
  48 jstack.4440.threadHigh.103713.178859435-
  51 jstack.4440.threadHigh.103724.736087099-
  57 jstack.4440.threadHigh.103736.376659166-

Here we see the thread dumps taken over time continue to consistently have a higher number of threads most likely waiting to compile LESS. The below thread dump shows samples us the entire stack trace.
