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:) best regards taseff
