webhostingtalk.com my.cnf ?

2025-04-07

i have a forum thats almost as busy as webhostingtalk.com but the server is so much loaded although its dual xeon 2gb ram dusl 73 scsi with 2gb swap

my my.cnf is:
[mysqld]
set-variable = query_cache_type=1
set-variable = query_cache_limit=10M
set-variable = query_cache_size=150M

set-variable = max_connections=512
set-variable = ft_max_word_len=30
set-variable = ft_max_word_len_for_sort=20
set-variable = ft_min_word_len=2
bind-address = 127.0.0.1
port = 3306

set-variable = delay_key_write=ON
set-variable = delayed_queue_size=10000
set-variable = delayed_insert_limit=50
set-variable = max_delayed_threads=8

set-variable = connect_timeout=10
set-variable = interactive_timeout=100
set-variable = wait_timeout=60

set-variable = low-priority-updates=ON
set-variable = key_buffer=550M
set-variable = table_cache=5500
set-variable = sort_buffer_size=5M
set-variable = join_buffer_size=5M
set-variable = read_buffer_size=5M
set-variable = read_rnd_buffer_size=5M
set-variable = tmp_table_size=400M
set-variable = myisam_sort_buffer_size=256M
set-variable = thread_cache=256
set-variable = thread_stack=256000
set-variable = thread_concurrency=4
server-id = 1
set-variable = max_allowed_packet=20M
set-variable = flush_time=9600

skip-bdb
skip-innodb

and using a script i found at rackshack forum's gave me this output:
