Maybe you have some long running query that blocks everything else? show variables and show status alone don't tell much.

Increase it depending on how much memory you have and what else runs on the server, and how big your database is. For a dedicated database server, 1/4 of the main memory sounds nice, given that your keys are larger; else, make it fit the keys size. | max_allowed_packet | 65536| | max_connections| 90 | | max_join_size | 4294967295 | | max_sort_length| 1024 | | net_buffer_length | 8192 | | port | 3380 | | record_buffer | 131072 | | skip_locking | 0| | sort_buffer| 2097144 | | table_cache| 64 | Opened_tables below indicates, that you could do with more. Try 128 and check whether Open_tables stays below that limit here.
