#

are you seeing it on just the first call or on subsequent calls (on the same procStretchDIBits) as well?

#

the LoadLibrary and GetProcAddress may contribute quite a bit of time if that’s happening at call time (just the first time, of course)

#

hmm, i’d probably take an xperf trace and see if you’re getting hosed by context switches or something

#

10ms should be long enough to get some granular information on individual calls
