Very slow linking process in VS C++ 2012

Hi,

I would like some guidance and help for a problem we're facing in VS 2012 (C++ native project). We had been using VS2010 for our project, and recently we'have upgraded to VS2012. Now we're facing a very nasty problem, that of extremely slow link times. Under normal circumstances, our project takes about 20 min to compile and link. The usual link times are about 1-2 minutes. However, since upgrading to VS2012, sometimes, maybe 1 in 5, the link times spike to 10-12 minutes, without any obvious reason. This happens on every windows machine running VS2012.

So, I would like to ask if the linker in VC++ 2012 has some differences from the one in VC++ 2010, and if there are some directories that hold caches, that we should clean. I would like also to mention, that some of our headers/libs are on a network and that with VS2010 this problem did not occur. Also, I would like to mention that often VS2012 seems to be in an inconsistent state, where breakpoints are not hit, and code seems not to be called. In these cases we usually quit VS or even restart the machines.

I've also posted the same problem here, but was told to ask for help, from the VC team. 

Thanks.
