Understanding User and Kernel Mode

I can confirm those values on my Vista 64 machine (Intel Core 2 Duo E6600, roughly the same results).

So SEH on 64-bit Vista is over four times slower than gcc’s exception mechanism, and going through the new WOW 32/64-bit translation layer doubles that time.

This is amazing. I’ll have to cook up test cases for C# and Java, though Java probably won’t give me kernel timing.
