Thank you for your answer. However, i do insist. I use again the file created with "seq 10000 > 10k" and still look-up the string "9999" inside it. I perform: strace -o vi.out /usr/bin/vim 10k and inside vi: :0 /9999 :q Without snapshot, vi.out contains 15133 lines With snapshot, vi.out contains 426553 lines. Huh? Without snapshot, the 6 lines: ------------------------------ select: sel.always_ready 0 select: sel.wait returns 0 select_stuff::cleanup: calling cleanup routines select_stuff::destroy: deleting select records select: recalculating ms select: ms now 0 ------------------------------ occur about 450 times With snapshot, the 6 lines: ------------------------------ select: sel.always_ready 0 select: sel.wait returns 0 select_stuff::cleanup: calling cleanup routines select_stuff::destroy: deleting select records select: recalculating us select: us now 0 ------------------------------ occur more than 69000 times Something is probably wrong near here. Please tell me what i should experiment next. Al least i have found a wrong line in select.cc: line 4, the copyright year is missing. ;-) Regards, Denis Excoffier. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
