Project-system: Scalability performance tests should GC before snapshotting working set

[davkean]

The performance tests should run the following before snapshotting working set:

C# GC.Collect(); GC.RunPendingFinalizers(); GC.Collect();

[davkean]

Looks like this is the code that grabs the memory: https://devdiv.visualstudio.com/InternalTools/_git/Scalability%20Measurment?path=%2Fsrc%2FVSCMD%2FNativeMethods.cs&version=GBmaster&line=146&lineStyle=plain&lineEnd=146&lineStartColumn=44&lineEndColumn=67.

The fix isn't that simple unfortunately. The code you linked runs in the driving console process, not devenv.exe.

[davkean]

There's actually a command called "Tools.ForceGC" that does a GC - assuming we have access to DTE out of proc in the console app, we should be able to run that command.

Forcing a GC is well understood best practice in APEX. There is support for this in APEX here. It uses the DTE apis as @davkean describes
