I'm seeing this too.  I reverted back to 5.1.1 and the problem disappears.  It was killing me on the last couple releases.

Now I'm seeing the CPU drop back to single digits - whereas before they were constantly spinning.

Hello Markus,

Which build of ReSharper exactly do you have installed at the moment? Do
I understand correctly that you didn't notice this problem with previous
builds? Thank you!

With one difference: Now all cores are busy.

Just me?

I first noticed this Friday with 5.1.2 1754 then upgraded to the newest
5.1.2 available on Friday (1756) and nothing changed. 5.1.1 works
significantly better.

Hello Markus,

Could you please elaborate more on this problem? Which actions lead to high
CPU usage? Could you please capture a performance snapshot with the latest
build of ReSharper 5 following the instructions at http://confluence.jetbrains.net/display/ReSharper/ReSharperPerformanceProfiling+Instructions
and upload it to ftp://ftp.intellij.net/.uploads/?

Andrew,

build of ReSharper 5 following the instructions at http://confluence.jetbrains.net/display/ReSharper/ReSharperPerformanceProfiling+Instructions


concerning 8.d (Press 'Get Snapshot' button on the 'Control Profiling'
window):

Should I do this while CPU usage is extremely high or afterwards?

Hello Markus,

The best result will be achived if you press 'Get Snapshot' immediately after
Visual Studio with ReSharper has stopped pegging CPU. This way, we will get
a full picture of what was going on. Thank you!

My EAP build 1758 just expired now which reminded me painfully how fast and responsive the VS2010 IDE is without R#. This issue is really, really annoying.

Build 1760.3 almost convinced me that the problem is finally fixed, ran nice and fast until the moment when I started switching solutions. From here on it came to a crawl with every keypress.

Hello Andreas,

How big are the soluions you're switching between? How many times do you
switch until Visual Studio with ReSharper starts to crawl? Thank you!

Solutions are from very small (one project, 5 classes) to medium size (20 projects, ~1000 classes), mostly C#, web projects included in some solutions. Most of the projects include external references, which is something that R# doesnt like much anyway (there are a bunch of reported exceptions on that topic).
After two or three switches, forth and back between solutions, it starts to slow down. Only restarting VS2010 helps. R# reported mem usage is always around 80mb.

Hello Andreas,

I've assigned a task to our QA engineer: http://youtrack.jetbrains.net/issue/RSRP-199959
and we will try reproducing this behavior on our side. Thank you!
