Re: 1.7] BUG - GREP slows to a crawl with large number of matches on a single file
OK. Here is a simple test case:
X=100000
while [ $X -gt 0 ] ; do echo "The quick brown fox jumped over the lazy dog"
; let X=X-1; done > testfile
time grep dog testfile | wc
Cygwin 1.5:
real 0m0.219s
user 0m0.232s
sys 0m0.045s
Cygwin 1.7:
real 7m46.575s
user 7m14.138s
sys 0m0.076s
While using sed on Cygwin 1.5, I get the reasonable result:
time sed -ne /dog/p testfile | wc
real 0m1.229s
user 0m1.202s
sys 0m0.046s
