Spell Checker - High memory and CPU usage in a big solution

created 5 months ago

Hi, I recently started noticing that when I have CodeRush enabled, the ServiceHub.RoslynCodeAnalysisService.exe is using a lot of memory and is constantly using CPU causing the fan of my laptop to be quite loud.

Currently it's constantly using 5-10% cpu and is using almost 14GB of memory (while typing this message it went from below 13.5GB to 14.3GB when I'm not even doing anything). When I first open the solution at work, which is quite big at around 250 projects, the memory usage is around 5-6GB. But when I start working then it just keeps increasing and is never going down. Also opening VS suggestions is taking a lot of time.

When I disabled the CodeRush extension, the memory usage is around 3GB with the same solution and is not increasing constantly and suggestions are also much faster.
I tried to gather a log with the performance monitor, but when I stop collecting the logs then a log file is never written to or displayed.

How can we find out what is causing this memory usage?
