As it is now, mysql is configured to occupy about 600M RAM, and queries per second avg goes up to about 100, yet under the top load it seems to be not enough. Here are the config options: set-variable = key_buffer=512M set-variable = max_allowed_packet=1M set-variable = table_cache=512 set-variable = sort_buffer=8M set-variable = record_buffer=1M set-variable = myisam_sort_buffer_size=64M set-variable = thread_cache=16 set-variable = max_write_lock_count=10 set-variable = thread_concurrency=8 The server itself is 2x PIII Intel Xeon 700 MHz, Intel KOA4 platform, with 4G RAM. Mysql 3.23.47 (binary distribution), FreeBSD 4.5 system. All mysql queries are rewritten so the INSERT/UPDATE's has been reduced or replaced by DELAYED as much as possible, to ease mysql locking. The mysql tables are indexed, all documentation from the main mysql site having been studied. And under the top load the mysql starts locking anyways. So what can be the best ways of helping it: - Changing mysql options, may be increasing key_buffer some more or what else? - Adding 2 more CPU's to the server (it can bear up to 4 CPU); - May be there can be some other ways? Thanks in advance!
