Visual Studio compiles slowly, low CPU usage

Re: Visual Studio compiles slowly, low CPU usage

I have network shares but I don't think that they are in my PATH (but I'm
not sure). I'll check that tomorrow (at my office). Thanks for the pointer.

Yes and I did not see any significant activity but I need to do more
research with perfmon. I did not monitor network or disk activity. Before
going too deep into monitoring, I wanted to check if anybody had experienced
something like this, and get the most obvious pointers.

So, I'll investigate the network shares in %PATH% (see other replies) and
I'll do a bit of perfmon testing if I don't find anything.

Re: Visual Studio compiles slowly, low CPU usage

No, I had run Windows Update a few days before the attack and my machine was
protected. Also, I ran the AntiVirus after the attack and it did not find
anything. So Blaster's not the culprit.

Hi Bruno, Are you on a Domain at work? If so see

318738 FIX: .NET Programs Are Slow to Load When Running Under a Domain

http://support.microsoft.com/?id=318738

This is 'supposed' to be fixed, but might be worth a look. You may need to to have an ASPNet account set up according to the article..

Re: Visual Studio compiles slowly, low CPU usage

Hi Scot,

Yes, we are running under a domain at work, and not at home. I looked at the
link but I don't think it explains our problem:

* The problem is not with the .NET apps that we create but with Visual
Studio .NET itself.

* Visual Studio starts normally (so the problem is not at load time). The
problem shows up at the end of compilation: CPU usage is very low (2% or
less) and stays like this for more than 1 minute before completing and
moving to the next project of our solution.

* We are running Studio 2003, so the underlying framework is 1.1 rather than
1.0.

One note: our solution mixes J# and C# projects. The first project that
takes the longuest to compile is a J# project which is referenced by all our
other projects. Depending on what we are building, we have between 5 and 46
projects in the solution but the problem does not seem to be related to the
number of projects in the solution.

Also, recently we have rewritten our resource handling to use the .NET
mechanisms (resx files) rather than our old Java scheme, and it seems that
the slow compile pb has worsened at about the same time. So, it may be
related to the build of satellite assemblies.

What I can't understand is why the compiler sits almost idle for long
seconds before completing compilation. It really looks like it's waiting for
some kind of network response (from the domain controller???).

Bruno.

Re: Visual Studio compiles slowly, low CPU usage

Yes, BUT the .Net environment somehow has to see the ASP net User (Acording to that article) thats why I brought it up. Make sure that account exists and has proper
permissions...

Re: Visual Studio compiles slowly, low CPU usage

Hi Scot,

The ASPNET user exists (we really need it because we are developing a web
app). So the problem must be somewhere else.

Thanks anyway for the info.

Re: Visual Studio compiles slowly, low CPU usage

Could Name resolution possibley be the issue? Perhaps you could put an entry for the machine where the files are located in the HOSTS file and see if that resolves the problem.
Its a long shot but it could be that simple...

Re: Visual Studio compiles slowly, low CPU usage

Hi Scot,

The files (Studio and source) are on the local disk.

Actually, I crossposted on microsoft.publi c.dotnet.vjshar p and Michael Green
(MS) suggested that I unplug the network cable.
I tried it and it fixed the problem. The results are the following:

With network cable:
First project: 110 s
Whole solution: 240 s

Without network cable:
First project: 20s
Whole solution 150 s

So, the compiler wastes 1 min 30 s if the network cable is connected. And
only the first project of the solution is affected. Strange!

This shows 2 things:

* Everything is installed locally, because I can build with the network
cable unplugged.
* VStudio is doing something strange over the network at the end of the
first project build.

Michael suggests that I run netmon to investigate what is going on through
the wire but I don't have time to investigate this right now.
I just turned my machine around so that I can easily unplug the net cable
before compiling. Problem is that the fan is a bit noisy!

Bruno.

Re: Visual Studio compiles slowly, low CPU usage

Problem could be name resolution as I mentined before... Put the IP Address of teh Web Server in the Hosts file and see what happens... Checking a Netmon trace is probably
definately the way to go to resolve this in the future.

Re: Visual Studio compiles slowly, low CPU usage

Hi Scott,

I don't understand which Web Server you are talking about. Everything's
local: source code, dev tools but also testing/debugging environment. We
test on localhost (so each of us can test on his own machine).

The only thing that's remote is our CVS source control but we got rid of the
IDE integration and we run WinCvs on the side (and we access it by IP, not
by name).

So, do you mean that I should put "localhost" in my Hosts file? I'm a bit
lost.

Bruno.
