I'm trying to run some scripts off of a slow network share, and it

Looking at an strace (attached) via 'sort -n' shows a LOT of time
being spent in read(), apparently just after (caused by?) an fstat(),
which means this feels like an inefficiency somewhere in Cygwin's
POSIX emulation. Other than "RTFSC", does anyone have any ideas what I
could do (workarounds, etc) so that I can run scripts in a reasonable
amount of time? (Might this have anything to do with my share being
non-writable?)
Take a look at the -x, -E, and -X flags of 'mount'. Perhaps these will help
you.
Hmm, those are mutually contradictory... guess I'll "experiment". Out of
curiosity, what are any of these expected to do?
Sorry for the .bz2, but 248k seemed a little excessive :-).
And actually sending unsolicited straces to the list is discouraged.
Sorry, didn't know that... it seemed relevant.
Somewhat OT, why does 'strace bash -c foo > /foo_strace' generate a
file with DOS line-endings? None of my mounts are 'textmode'...
'strace' does not use cygwin1.dll.
Ah, makes sense, thanks.
