Omnisharp-vscode: C# project has unusably slow intellisense

Hi, on recent versions of Code (.10.6 and I believe a few versions before) I've been having terrible problems with completion on a C# project. Intellisense completion will work fine for a little bit, then start coming up extremely slowly, and then will not come up at all. Error checking is also extremely lagged. After a little bit it will start working again. It seems like Ominsharp is completely dying and restarting in the background. It feels like switching files will cause it to happen more often. It's not something that resetting Code seems to help with, and happens at least every minute so Code is completely unusable on this project. Any help would be super appreciated!

This is on Mac OS 10.11.1 using a rather large Unity project.

Here is a zipped MOV file of the issue, it starts really breaking at around 1 minute mark.

Here is my output log:

Hi all, is there anything at all I can do to help track down this bug? I am still stuck on Code .10.3, .10.7 still has the same issue. I would kill for a fix!

Not 100% sure if this is identical, but .10.9 is doing the same thing. This is now happening on a much smaller project.

Below is the output from .10.9:

I realize that it's been a long while since there was an update on this issue. Are you still experiencing this problem? Note that we've just released a beta of the next release, v1.3.0-beta1. Please try that out and let us know if it works better for you.

@DustinCampbell I just tried 1.3.0b1 and same issue. I'm not seeing any output in the omnisharp log when it happens though. I can make it happen almost every time when I save the the file I'm working on.
Here is a video of the issue using 1.3.0b1 and Code Insiders 1.4.0. I am holding the command key the entire time:
VSCodeBug.mov.zip

@DustinCampbell Tried out 1.3.0b1 as well. Fresh VSCode install, the same project I was trying to work with the last time I investigated the issue.

Seems like OmniSharp doesn't start properly at all, there's no "usages" for variables and functions, etc.

Here's the initial startup log:

[INFORMATION:OmniSharp#MSBuild] Loading project from '/Users/user/Documents/Eclipse/Something.something/Assembly-CSharp.csproj'.

And here's the log that keeps popping up each time I try to reboot the OmniSharp:

Note that I deleted/changed some private things, like the title of the project or script names.

This should be fixed with the 1.5 release. My expectation is that this PR will fix the issue: https://github.com/OmniSharp/omnisharp-vscode/pull/902

DustinCampbell on 11 Nov 2016

This is not fixed at all, codelens is so heavy for omnisharp to process as nothing is cached. No request are cancelled either (after switching editor tabs, old request are still running)

Omnisharp just chokes up at some point, especially with codelens heavy (many referenceable items) files. Switching a few times between files is also a good way to kill omnisharp.

NinoFloris on 29 Nov 2016

@NinoFloris, could you file a new issue? The issue here has been reported fixed in another bug report by those that filed this issue.

DustinCampbell on 29 Nov 2016

Well it is directly linked because the singlethreadedness was a way to at least throttle the incoming barrage of work. This surfaces now that they are run concurrently

NinoFloris on 29 Nov 2016

Sorry. I'm not sure I understand what you mean. Again, please file a new issue so that we can dig in.
