The first priority id to completely stop swapping. It's a performance killer.

Once that's done, and there's more memory available, re key_buffer_size, key_read_requests / key_reads is 2.75 billion to 1. Start by getting it down to 1000:1.

If you can't think of why performance_schema is enabled, disable it.
