When trying to update a lot of issues at once, the initial bulk ops screen may some times timeout.
This happens because there can be too many fields that would be configured at all issues page, which will happen more if majority of those fields are custom fields

Right now, we haven't fixed it yet. We're looking into ways to make it better, but we know it's a big problem, especially when you're trying to update a lot of issues all at once.

Issue Summary

Doing a bulk update with lots of issues and custom fields makes everything slow.

URL Affected: BulkEdit1.default

Steps to Reproduce

1. Go to the Advanced Issue Search and pick more than 150 issues to update.

1. Click on "Bulk change all X issues." 

1. You'll notice it's really slow or might even time out before you finish.

Expected Results

You should be able to go to the landing page.

Actual Results

It gets really slow, and sometimes it times out.

Workaround

For now, the only thing you can do is update fewer issues at a time, or configure lesser number of fields on the List issue view page
