> 
> About a week ago, my build times took a dramatic change with no identifiable
> change made in my setup.
> 
> Setup:
> Windows 7
> QNX 6.5.0 SP1 (build target is 6.4.0 though) IDE 4.7
> 
> Symptoms:
> A clean which used to take a few seconds now takes a few minutes.
> Builds which took a minute or so now take 3 to 4+ minutes.
> Creating a new project also takes much longer than normal.
> Importing a project also takes much longer than normal.
> 
> Attempts to remedy:
> I tried creating a new workspace, but importing projects still took a long time.
> Creating new projects also took a long time.
> 
> Uninstalled QNX and reinstalled just 6.4.0. This is what I'm currently running
> with no changes. Builds take a very long time, new projects or importing
> projects take a long time, etc.
> 
> I haven't found anything on the web to explain my issue. The .log file in the
> .metadata folder of the workspace doesn't have anything unusual. I don't see
> anything unusual in the Task Manager while doing a build.
> 
> Anyone have any suggestions?
> 
> This setup was working fine and changed over a weekend through nothing I did
> (that I'm aware of).

You could check to see if a new anti-virus was installed, or updated.

Do you have your build folder excluded from Active/live protection?

you could possibly try disabling your anti-virus to see if that makes the difference.
