recommendations may be inaccurate Enable the slow query log to troubleshoot bad queries Adjust your join queries to always utilize indexes When making adjustments, make tmp_table_size/max_heap_table_size equal Reduce your SELECT DISTINCT queries without LIMIT clauses Increase table_cache gradually to avoid file descriptor limits Variables to adjust: join_buffer_size (> 8.0K, or always use indexes with joins) tmp_table_size (> 32M) max_heap_table_size (> 32M) table_cache (> 1024) open_files_limit (> 2158) root@rider:~/tmp# On Thu, Oct 6, 2011 at 10:09 AM, Rik Wasmus <r...@grib.nl> wrote: >> thanks for the response -
