R# 5.1.2 performance issue

even if you note that you have made improvements in handling large files with R# 5.1.2 release this seems not to be the case for VB sources. I'm working under Visual Studio 2008 on a VB solution. The application is an old legacy one which was converted from VB6. When i try to edit large files, the class file i'm currently working on has aroun 11.000 lines, the edit performance decrease more and more, specially when there are many compiler errors (I accidentially pressed Ctrl-K-U twice because of the slow performance and therefore all the comments in the former uncommented code block where treated as normal code).  CPU activity of VS is very high and the cursor in the editor window don't react for seconds. When i take a look at the VS instance in the process explorer at this time i see that VS is busy doing garbage collection (60% .. 90%).

I notice that VS becomes slow with all R# releases except R# 4.5 when i work on a VB solution with large fiels and / or many compile errors.

After working a while with my large file i had to disable R#. Every 5 to 10 minutes the editor is not responsible for 2 - 3 minutes because of garbage collection.

Hello Klaus,

This is a known performance problem for such large files especially when
there are lots of errors since ReSharper tries to draw them all on the error
stripe. Nevertheless, could you please take a performance snapshot (following
the instructions at http://confluence.jetbrains.net/display/ReSharper/ReSharperPerformanceProfiling+Instructions)
and upload it to ftp://ftp.intellij.net/.uploads/, so that we could take
a closer look. Thank you!

i would like to take a performance snapshot but the instruction link you mentioned in your posting is broken. Also today i had the problem without any errors in the solution.
