3. Compile time may become very large for large test programs or heavy template usage. E.g. in one case, we had to split a test into three (Spirit's switch_p tests) in order to make testing feasible.
It is hard to know the overall effect without accurate timings. My personal belief is that on average the total time will drop. But we need timings to know for sure.
There are some cases when really big tests would certainly be slower. I had to split some of my Python container library tests into separate modules because g++ was starting to thrash the swapfile(s) on my home machine (with 256MB of RAM). I would guess that otherwise one big test module would certainly be faster, but there is a practical limit there somewhere.
Yes. GCC is a particular problem because of its tendency to run away with RAM. I even have trouble sometimes with a 1 Gigabyte system. --Beman
