Hi all,
i have machine with 2 x Quad Core Xeon cpu`s 2G ram and 4 3ware disks in
raid10. There is 6.2 Stable on it and mysql 5.0 from the ports.
The mysql is installed with the following build options:
WITH_XCHARSET=all WITH_OPENSSL=yes BUILD_OPTIMIZED=yes WITH_ARCHIVE=yes
WITH_FEDERATED=yes WITH_NDB=yes
I`m using libmap.conf with this in it:
[mysqld]
libpthread.so.2 libthr.so.2
This is what I have in my.cnf :
set-variable = key_buffer=1024M
set-variable = max_allowed_packet=64M
set-variable = thread_stack=1024K
set-variable = read_buffer_size=2M
set-variable = read_buffer_size=2M
set-variable = max_connections=350
set-variable = interactive_timeout=100
set-variable = wait_timeout=120
set-variable = max_user_connections=340
set-variable = query_cache_limit=1M
set-variable = query_cache_size=32M
set-variable = query_cache_type=1
set-variable = table_cache=1024
set-variable = thread_cache=128
set-variable = thread_cache_size=40
set-variable = thread_concurrency=16
I`m performing the following test with super-smack:
:~# time super-smack -d mysql
/usr/local/share/super-smack/select-key.smack 10 10000
the results are:Query Barrel Report for client smacker1
connect: max=1ms min=0ms avg= 0ms from 10 clients
Query_type num_queries max_time min_time q_per_s
select_index 200000 0 0 18599.71
I can achieve better performance even on my colleague`s notebook with
6.2 stable !?
I`ll be very thankful if someone can give me any ideas:)
Try looking at hard drive usage.
