Build 73 causes random, repeated CPU spikes

I finally had to uninstall Build 73. While it fixed some of the bugs that drove me nuts in build 72, it appears to have its own demons.

Specifically, my install causes the CPU load to spike to 100% at seemingly random times, but only while editing, during which the solution is temporarily in an uncompilable state. This did not happen prior to installing Build 73...

Doesn't happen to me. Probably should reload the OS on your machine.

I have seen this on occasion, but rarely (maybe once per hour).

Please do not reinstall your OS ;^)

Is there anything notable about your project (like 10s of thousands of
lines of code, hundreds of classes, ...)

By the way, HOORAY for "rename reference" and "implement ]]>"
intention actions... they are especially helpful while waiting for
"extract method" to arrive.

Rob Trainer's one of my colleagues and keeps bitching about me 'whining' on this message board. No chance of my reloading my OS on basis of his advice...

Our solution is fairly large, I guess, but we're just in the starting process - so far we have about 30000 lines of code spread over 8 projects - that's likely to grow to well over 100,000 lines of code and 10-12 projects...

The strangeness is that I don't remember this happening in build 72.

Is there any difference in the build #75?

Oskar,

in build 72 we made some enhancements to get rid of delays during typing.
It seems that there are still some performance issues like periodical spikes
which haven't
been resolved yet. We're going to deal with them in the nearest future.

Didn't realize it was out yet. Am installing now - will report back at the end of the day.

I have the same problem and it is almost a show stopper for me. I am not sure when it started (before build 73 I think). Build 75 does not solve the issue, in fact it may actually be worse (happens more often)

I will actually spike for a couple of minutes, and it probably happens 3 or 4 times an hour...argh.
Our project is not that big, maybe a couple hundred classes.

If I can I be of any assistance providing logs etc, let me know.

Scott,

what are the characteristics of the system you are running ReSharper on (CPU
& RAM size)? Do these
spikes happen during editing or some other operations? If this happens
during editing, how large the file
you are editing?

Thanks,
Dmitry

Pentium 4, 3Ghz, 2 Gig of RAM
Windows XP Pro SP1.

The files are not that big, one class per file, maybe a couple hundred lines at a maximum.

It is definitely during editing, sometimes during typing, possibly during pasting. I wish I could help you narrow it down, but currently it seems quite random.

I will start tracking when it happens, what I was doing, and what file/class I was in.

Thanks!

Ditto. Fairly small solutions (3-6 project), a few dozen classes. Fairly
small source files ~500 lines/class file... 2000-3000 lines for forms based
stuff.

Dell inspiron 8500, 1gb ram, not a lot of free disk space... maybe 5-7gb
free on 60gb drive. fixed swapfile size 1.5gb. WinXP Pro, current patches.
1920x1200, system font 120-150%, theme fonts Large.

Frequency bout the same... 3-4/hour. It's so bad that it's faster to kill
vs.net and restart than it is to wait for the spike to end (some never did).

Let me know if you need more details.

Been having .75 install trauma. Might be back up and running. Will post
observations later this afternoon.

I have turned off "Code Highlighting", the problem seems to have
disappeared.
I will turn it back on and see if I can get more specific.

Editing maybe too non-specific.?.? Possibly related to auto-complete
(auto-popup after 3 chars) or ^Space (et al). No obvious pattern at this
point.

For what it's worth, I have not experienced this after installing Build 75.

syntax highlighting enabled or disabled?

Ok - for the week or so I had build 75 installed I never encountered this problem. I installed Build 76 yesterday(?) and now it happens once or twice per hour. The last time VS hung for well over a minute. No idea if it has the same cause as before, but the end effect sure looks familiar...

Build 77 still has bouts of this - and it appears to be memory related. I'm assuming that the "Memory Usage" text in the status bar is something ReSharper adds - there seems to be a strong correlation between the CPU spikes/freezes and large amounts of memory being released.

Oskar,

Yes, the "Memory Usage" notification in the status bar is added by ReSharper
for diagnostics purposes. It shows the amount of managed memory used by
Visual Studio. If ReSharper is the only managed add-in you use then it is
quite close to the amount of memory used by ReSharper.

The CPU spikes are caused by the garbage collection. We are working on it.
