Yes.  There is one directory with 1900 files in it.
Using http://www.winehq.org/pipermail/wine-patches/2008-June/056508.html
and then doing WINEDEBUG=+timestamps,+file, I could
see that searching that directory for any particular file 
takes as long as 3ms, as measured by the time it took between

trace:file:wine_nt_to_unix_file_name L"\\Program Files\\Microsoft
SDKs\\Windows\\v7.0\\Include\\typeinfo" not found in
/home/dank/.wine-chromium-tests/dosdevices/c:/Program Files/Microsoft
SDKs/Windows/v7.0/Include

and the trace message immediately before it.

Furthermore, adding a kludgy bloom filter cache to GetFileAttributesW
halved the time to compile base (from 43 seconds to 24 seconds),
so that's definitely the sore spot.  I'll attach the bloom filter patch,
but it's a total kludge, so it's only good for demonstrating the bottleneck.
