FWIW:

The difference between cygwin-x86 and win32-x86-cygwin is the OS that EPICS
is interfaced to.

win32-x86 (native win32 OS, x86, M$ compiler)  
win32-x86-cygwin (native win32 OS, x86, cygwin gnu compiler)
win32-x86-borland (native win32 OS, x86, borland compiler)
cygwin-x86  (cygwin POSIX emulation OS, x86, cygwin gcc compiler)

Last time I ran performance tests I observed that EPICS based on cygwin-x86
POSIX emulation on windows was substantially less efficient than EPICS based
on native win32-x86 on windows. Also, depending on how cygwin POSIX
emulation was implemented time stamps might be less precise on cygwin-x86
(this could be investigated by running epicsTimeTestHost on both versions).
