hi,
I did some testing an a supermicro 2 x 4 core xeon server under 64bit
"7.0-STABLE #1: Fri Jul 4". when we first tested the system under load
(2000 apache threads) the system performed bad compare to other dual
core systems under the same workload.
the 8 core system had 0% idle time and almost 100% system load. I could
not find out what the load was. disk IO was close to zero during that time.
because of that I checked the sysbench results with this test:
sysbench --test=oltp --mysql-socket=/tmp/mysql.sock --mysql-user=root \
--max-requests=0 --max-time=60 --oltp-read -only=on --num-threads=$1 run
here are the sysbench results:
- 1 thread --------------------------------------------------------
OLTP test statistics:
queries performed:
read: 354774
write: 0
other: 50682
total: 405456
transactions: 25341 (422.34 per sec.)
deadlocks: 0 (0.00 per sec.)
read/write requests: 354774 (5912.82 per sec.)
other operations: 50682 (844.69 per sec.)
- 8 threads -------------------------------------------------------
OLTP test statistics:
queries performed:
read: 145166
write: 0
other: 20738
total: 165904
transactions: 10369 (172.75 per sec.)
deadlocks: 0 (0.00 per sec.)
read/write requests: 145166 (2418.54 per sec.)
other operations: 20738 (345.51 per sec.)
--------------------------------------------------------------------
during the 8 thread test "top" looks like this:
-----------------------------------------------------------------------------
last pid: 30104; load averages: 2.50, 0.65, 0.52 up 0+01:49:44 17:52:14
69 processes: 7 running, 62 sleeping
CPU: 5.6% user, 0.0% nice, 64.0% system, 0.0% interrupt, 30.4% idle
Mem: 44M Active, 296M Inact, 277M Wired, 84K Cache, 214M Buf, 15G Free
Swap: 16G Total, 16G Free
-----------------------------------------------------------------------------
software versions used:
- mysql-server-5.1.25
- sysbench-0.4.8
any ideas what I should look for or what to change?
I could supply more info if needed. dmesg appended.
thanks,
lutz
