Our entire development team here has been suffering from a strange VC IDE problem. I was wondering if any of you have come across this. Our project is pretty big. 10 dsp files around 4000 files and 3.5 million lines of code. Often during development, the IDE stops responding, the CPU gets pegged at 100 (or near there) and no redraws happen in the IDE. On my 650MHz machine (with 256MB of RAM) this state lasts 10-15 minutes and then all resumes. It got better when I added tons of header files to the MSVCINCL.DAT files is used to exclude files from the file dependencies. I talked to MS tech support and they said that it seems to be a dependency update pause (!). They said the file limit is around 9600 files so that isn't it. One of my co-workers got a GHz machine and the pause is barely perceptable. I was wondering if there are any work-arounds any of you know about? TIA Woolie
