Re: new benchmarks. WAS: FreeBSD MySQL still WAY slower than Linux

Localhost using unix socket.

In my first post in this thread, there are some numbers for connections from localhost, but using TCP instead of socket.

The numbers are roughly the same with HTT disabled. For example for libthr:

HTT disabled:
-----------
# date; for i in 1 2 3 4 5; do super-smack select-key-mysql.smack 10 1000 |
grep select_index; done; date
Thu Dec 1 13:50:24 EST 2005
select_index 20000 1 0 14749.36
select_index 20000 0 0 14838.91
select_index 20000 0 0 14913.73
select_index 20000 2 0 14230.60
select_index 20000 1 0 14288.65

HTT enabled:

grep select_index; done; date
Wed Nov 30 22:47:26 EST 2005
select_index 20000 1 0 14375.95
select_index 20000 0 0 14392.69
select_index 20000 0 0 14478.93
select_index 20000 0 0 14371.66
select_index 20000 0 0 14416.07
Wed Nov 30 22:47:33 EST 2005

For linuxthreads and libpthread, the numbers are all within the same margin
as the other post as well.

Cheers

Are you running super-smack on localhost or from remote boxes?
