UBB.Developers Forums Community Development Programming MySQL and Server Configuration Why my tables produce big overhead.

Hi

Thanks for the respond.
Please take a look at the attachment to show you the 'overhead' that I have. This number is growing fast, I just optimize/repair 12 hours ago. In 2 days it should be about 200,000 Bytes and it stops the mysqld.

Number of users that are on at any given time is about 300
I have attached the screenshot of my tables including the sizes, rows, and overhead numbers.

For information, I am using Single Xeon 2.4Ghz with 1024MB (512MB x 2), SCSI DRIVE. OS Fedora Core 1, Apache 2.0, Php 4.2.2, mySQL 3.23.58

Here is my my.cnf config:
[]
[client]
port = 3306
socket = /var/lib/mysql/mysql.sock

[mysqld]
port = 3306
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock

skip-locking
set-variable = max_connections=500
set-variable = myisam_sort_buffer_size=64M
#set-variable = key_buffer=16M
set-variable = key_buffer=64M
set-variable = join_buffer=4M
set-variable = record_buffer=4M
set-variable = sort_buffer=6M
#set-variable = read_buffer_size=2M
set-variable = table_cache=1024
set-variable = thread_cache_size=256
set-variable = wait_timeout=3600
set-variable = connect_timeout=10

[safe_mysqld]
open-files-limit=8192

[myisamchk]
set-variable = key_buffer=256M
set-variable = sort_buffer=256M
set-variable = read_buffer=16M
set-variable = write_buffer=16M
