FreeBSD MySQL still WAY slower than Linux

I tried some benchmark testing on a Dell 1850 5.4-Release-P2 with
generic kernel.
From what I have seen from your postings I was able to get a higher
supersmack result, 23626.76 .
I compiled 4.0 MySQL with some optimizations
portupgrade -RN -m 'BUILD_STATIC=yes BUILD_OPTIMIZED=yes'
/usr/ports/databases/mysql40-server/
Downloaded and installed the supersmack source from here
http://vegan.net/tony/supersmack/super-smack-1.3.tar.gz
with just ./configure --with-mysql
Copied the default large my.cnf profile
cp /usr/local/share/mysql/my-large.cnf /var/db/mysql/my.cnf
# super-smack /usr/share/smacks/select-key.smack 50 1000
Query Barrel Report for client smacker1
connect: max=44ms min=11ms avg= 20ms from 50 clients
Query_type num_queries max_time min_time q_per_s
select_index 100000 3 0 23626.76
If I delete the /var/db/mysql/my.cnf and restart mysql so I get default
configuration, I get 13398.76
# super-smack /usr/share/smacks/select-key.smack 50 1000
Query Barrel Report for client smacker1
connect: max=29ms min=7ms avg= 17ms from 50 clients
Query_type num_queries max_time min_time q_per_s
select_index 100000 7 0 13398.76
For me this is as fast as I need my database to be but I can understand
there is a difference here between FreeBSD and Linux that would make you
prefer it as the db OS choice.

Mike
