Memory Leak In Browsers

[Ant1]

We are currently on Helsinki and I've notice that on both Chrome(Version 59.0.3071.115 (Official Build) (64-bit))  and IE11 there seems to be very high memory useage which eventually degrades my PCs performance.  I've noticed this on two separate PCs and i've even re-installed the OS on one of the PCs to make sure there wasn't anything else causing the issue.  I understand Helsinki was supposed to address this issue that was reported back in the Geneva release.  I've even adjusted some of Chrome's own tab settings and nothing seems to work.  Strangely enough, it even happens when I just have our production instance open and we don't build directly in production.  This DOES also occur as we develop in our DEV instance.  Having two tabs open, one in PRD and one in DEV, each tab is using 1.5GB and the other 500MB of RAM.  I find this strange and the other ServiceNow Sys Admin in my group is also experiencing similar issues.  The fix seems to close to tab and open a new one.  However, sometimes when you're in the middle of developing something, it's difficult to do that.  

Thanks,

Anthony

Hi Anthony,

That sounds really odd. In my case it's very often that I have about 11 open tabs with various instances running in Helsinki and haven't experience the issue that you're mentioning.

It sounds like you may have some client script running in your instance that may be causing the degradation. Doing a profile of your browser session may be the best way to identify what could be causing the issue.

Thanks,

You may also want to test an instance from the developer program (developer.servicenow.com) and see if it causes the same performance issue that you're experiencing.

Thanks,

I will definitely try both of your suggestions.   Thank you for the feedback!

Forgot to add; perhaps an advice will be to go to your client scripts and your UI scripts and sort these by updated date. Take a look to those recently modified (within the timeframe you started experiencing the performance problems) and try to see if these could be the ones contributing to the problem.

Thanks,
