Package: grep
Version: 2.5.1-1
When I try to use the latest "grep" to search a pattern in a 100-KB file,=
=20
it is considerably slower than previous version of grep.
Here is a time comparison with grep v2.4.2-3 on the same
machine.
# using grep v2.4.2-3
$ time ./grep-old test file |wc
2232 6696 44261
real 0m0.058s
user 0m0.060s
sys 0m0.000s
# using grep v2.5.1-1
$ time grep test srcfp/a |wc
2232 6696 44261
real 0m10.497s
user 0m10.430s
sys 0m0.010s
Is there any problem with the algorithm used in the latest grep?
I am using Debian sid, kernel-2.4.18 and libc6 2.3.1-11 on
a PIII 700MHz machine with 384MB RAM.
Thanks!
