Hi, I wish to tune our MySQL Server Parameter to increase the speed of Join. I was trying to do a simple join with two tables. One is big (~2,500,000 records); the other one is small. The current join seems to take forever to finish even on the indexed attribute.
I am trying to learn from http://www.mysql.com/doc/en/Server_parameters.html but not confident enough to play with our server yet. Any advice will be much appreciated. I am running mysql3.23.49 on linux7.3 with 4 GB memory. So I want to try the following from that doc: shell> safe_mysqld -O key_buffer=64M -O table_cache=256 -O sort_buffer=4M -O read_buffer_size=1M & My questions: if I run the above command (as root), should I run it every time when the server starts? If so, how can I set the above option automatically when server starts. Thanks! Qunfeng Dong __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
