I've looked through some of the lists here and have seen super-smack
results in the 42k qps range on a 2 dual core opteron system. I'm able to
get up to about 34k with the wide at the back of my server whilest rubbing
the side of it.
Here's what I've done:
built both mysql 5.0 and 5.1 from ports with build_static and
optimazations on.
changed the clock to TSC
added the following to my /etc/libmap.conf file:
[mysqld]
libc_r.so.5 libthr.so.2
libc_r.so.6 libthr.so.2
libthr.so.2 libthr.so.2
libpthread.so.1 libthr.so.2
libpthread.so.2 libthr.so.2
And this is about the best result I get:
2950# super-smack -d mysql select-key-mysql.smack 10 10000
Query Barrel Report for client smacker1
connect: max=200ms min=0ms avg= 20ms from 10 clients
Query_type num_queries max_time min_time q_per_s
select_index 200000 0 0 34440.88
Are there any other optimizations I need to do to mysql or freebsd? I'm
still not 100% convinced that I've done everything I need to use libthr
instead of libpthread.
on UP people recomend to use TSC instead of acpi timer
He uses the TSC already... but nobody suggested the gettimeofday()
wrapper so far: http://wiki.freebsd.org/MySQL
