So, when I switch tabs I get a 2 to 3 full second delay before the active tab UI switches and before the content area switches. This is on Win8[.1] (OS version: 6.3.9600) and I have not yet tried in Safe Mode. I do have (and use) chatzilla, but I was able to reproduce the issue prior to starting chatzilla in this session. Pasted below is my about:support info, followed by my about:tabs info (from glandiums tab counting extension) This is with today's Dev-Edition (5-22) and I updated from at least Monday 5-11 as the oldest possible, where I didn't experience this issue. (If you can't reproduce a similar issue, I'm happy to help bisect) In between that last build and this one I did an update (that was staged earlier) and then got the doorhanger prompt about e10s "is coming soon" I selected "NOT NOW". incase that matters. If you need more info from me, it is best to use a needinfo for a fast turnaround. With this much of an issue for me, I worry that users will abandon Firefox Dev Edition (or firefox entirely) if they experience this much of a delay. ==================== Application Basics

FWIW there is https://bugzilla.mozilla.org/show_bug.cgi?id=1166132 on file about creating a regression test for tab switching.
Interestingly, tab switching in chatzilla itself, is still instantaneous to the eye.
Can you give us a performance profile, Callek? https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Profiling_with_the_Built-in_Profiler
Flags: needinfo?(bugspam.Callek)
As said in IRC, after I saw the n-i my tab switching emmediately jumped down to an average of ~0.5s each. Here is the profile for this session, I'm about to restart and see if a new launch exhibits the previous longer delay http://people.mozilla.org/~bgirard/cleopatra/#report=0dba7dc7010f57d636717c24519b7d8be714c691
Flags: needinfo?(bugspam.Callek)
I'm seeing a lot of traffic over the multiprocess shim layer (which is enabled regardless of whether e10s is enabled or not). I suspect this is probably traffic caused by LastPass, and that might explain why you're seeing a variety of speeds - it'll probably get worse if you view very complex pages with many DOM nodes. If you disable LastPass, does the performance get better?
Flags: needinfo?(bugspam.Callek)
After restart with lastpass disabled: http://people.mozilla.org/~bgirard/cleopatra/#report=67842e7554a0e820d37ee866ecc13d9de4248199 Things also seem much better. Kinda expected that disabling e10s wouldn't have caused such a severe perf regression though... Kinda sucks for any addon author dealing with this, and even more so for users who don't know why *Firefox* suddenly is starting to misbehave. Even worse, for the shear number of passwords I have, and because Mozilla OpSec told me to use LastPass instead of storing in Firefox, I'm kinda locked to LastPass until OpSec recommends something better and/or Firefox's Builtin manager improves :/
Flags: needinfo?(bugspam.Callek)
This last profile shows Google Drive doing some pretty heavy stuff in JS, and blocking the main thread. So I think we've identified LastPass as the culprit. What's not great is that LastPass is causing lots of shim traffic _despite_ e10s being disabled. If there's been a serious performance regression with _non-e10s_ with LastPass due to the shims, that's probably something we should fix ASAP, since the shims are now on Aurora. Callek - can you please file a new bug with your profile from comment 4, Cc'ing myself, :billm and :gabor, and describing how you were hitting this performance bottleneck despite e10s being disabled? That bug should probably be in Firefox :: Extension Compatibility, and block bug 1116854.
Blocks: 1167667
Mike/Justin, with bug 1167667 closed, is there still something to be done here, or should we close this as WFM?

Flags: needinfo?(bugspam.Callek)
Yeah, I think that's fine. Callek, please re-open if you're still seeing this.

I use lastpass, and iirc I disabled e10s due to this (and other) bugs. I am on aurora though so I may have not noticed any recent 're-enable e10s and see how it works' moments. Though based on r-d and related discussion it sounds like its not being enabled for lastpass users in the wild atm anyway.
