Re: MyISAM Query Performance

[Rick James]

If there is nothing but SELECTs going on (not even replication), then stalls should not happen.

To assist in analyzing slow SELECTs, please provide
* SHOW CREATE TABLE tbl\G -- engine, indexes
* SHOW TABLE STATUS LIKE 'tbl'\G -- sizes
* EXPLAIN SELECT ...\G -- clues of inefficiencies
* SHOW VARIABLES LIKE '%buffer%'; -- cache size
and surround them with [ code ] and [ / code ]

That is, even if the stalls do happen, perhaps we can optimize things to lessen the problem.
