Hello All, I have a new install of CentOS 5.5. 64bit running MySQL 5.5. This box has 8GB of memory and is running nothing else other than mysql.
Shortly, I will be copying over a 80GB database from a Mysql 4.1.x server, and need to repair/upgrade most of the tables. I'm using myisamchk to do most of this, and I'd like to know the best settings for myisamchk to best optimize all the available memory to get the best performance out of myisamchk. I can have the mysql server down while I'm doing the rebuild, so essentially, the only thing running on the box will be myisamchk. I think these are the most important settings, but there could be others I am not aware of: --sort_buffer_size --key_buffer_size --read_buffer_size --write_buffer_size In case you're asking why I'm using myisamchk, I have found that it is by far the fastest way to rebuild/upgrade large MYISAM tables and indexes (I have posted about this before). -Hank
