ack2.08 slower than ack 1.96 when searching in Linux kernel. #339

Closed kojustin closed 8 years ago

kojustin commented 11 years ago

I've noticed that ack2 feels significantly slower than ack1 in a lot of uses. Here's one particular test case. With the current Linux stable kernel 3.10.9, the following query is 3x slower with ack2.08 vs. ack1.96

azawawi commented 11 years ago

Have you tried benchmarking that performance regression with newer perls?

kojustin commented 11 years ago

@azawawi, no I haven't I'm just using the default perl that came on my machine. Current stable perl is 5.18. Do you think that would make a difference? The test I ran above were running against the same version of perl.

azawawi commented 11 years ago

Ok I will double check it on win32 and linux to verify the performance regression on perl-5.12.4 and perl-5.18.1.

The file in question is the following extracted archive: ftp://ftp.kernel.org/pub/linux/kernel/v3.x/linux-3.10.9.tar.bz2

azawawi commented 11 years ago

Sorry for being late on this one. I can confirm this performance regression on perl-5.18.1 and perl-5.12.4. Please note that my i7 machine has 16GB RAM so file system caching can skew numbers a bit.

The following is the edited output for Perl v5.18.1:

# App::Ack 1.96
$ time ack FUSE_LINK fs
real    0m0.420s
user    0m0.376s
sys     0m0.024s

# App::Ack@2.08
$ ack FUSE_LINK fs
real    0m1.098s
user    0m1.060s
sys     0m0.028s

The following is the edited output for Perl 5.12.4:

# App::Ack@1.96
$ ack FUSE_LINK fs
real    0m0.053s
user    0m0.016s
sys     0m0.008s

# App::Ack@2.08
$ time ack -k FUSE_LINK fs
real    0m1.100s
user    0m1.040s
sys     0m0.044s

azawawi commented 11 years ago

NYTProf shows that App::Ack 1.96 calls next_text 251896 while App::Ack 2.08 calls does_match 1106050 times. Maybe file filters are different?

azawawi commented 11 years ago

strace-ing it.

$ strace -e trace=file ack -k FUSE_LINK fs | grep "Kconfig"

Basically App::Ack 2.08 is opening the same file a lot. For example open("fs/btrfs/Kconfig", O_RDONLY) = 3). Rough estimate is 7 to 2 file open operations for App::Ack 2.08 versus App::Ack 1.96.

ack as of 0dd3f43 is now slightly faster than ack 1.96 when searching the kernel.

kojustin commented 8 years ago

Sounds like this has been fixed for about 1.5 years now? Closing.

petdance commented 8 years ago

It's your ticket, @kojustin. Are you satisfied with the fix?

kojustin commented 8 years ago
