Guess I've not been paying attention... what type of problems have you seen with sendfile (TransmitFile) on Win32? We do have a performance problem (will leave out details unless your interested) but I was not aware of corruption problems...
The example which, I guess, was the impetus for this thread: http://issues.apache.org/bugzilla/show_bug.cgi?id=34037
I don't have any way of quantifying how frequent this is, but it certainly shows up on a regular basis.

Thanks, that's the buggy LSP problem (symantic AV is the likely culprit in this case. It handles TransmitFile but does not correctly handle offsets specified in the overlapped structure). I'd support disabling sendfile by default and publishing a performance tuning doc.
