The more attachments added to an issue the slower the performance on Jira.

Hi All 

I just wanted to find out if anyone is having performance issues on Jira when an issue has attachments.

So basically there is slowness when updating, commenting, transitioning , ..etc.  issues with attachments.

We are using MSSQL and are implementing daily maintenance as suggested by Atlassian.

We have tried disabling add-ons and enabling them, issue remains.

We have tested disk speed and DB speed those seem fine.

There is no noticeable network latency between Jira and DB.

This is a known thing in Jira.  Jira is not a file server, it is an issue tracker.

When you view an issue, Jira starts to load up the attachments into memory in case you want to use them, and that can become a problem when:

• You have added large files 
• You have attached huge numbers of files
• You have the attachments on an unsupported file system (or, if you're on Data Center, a supported one, which is still going to be slow to read)
• You have an app that is reading the content of a lot of data in files

You've taken a good look at a lot of the right places, and can rule out a couple of these (disk speed for example), so I suspect the problem is going to be simply the volume of files (number and/or size)
