Handler read retry Documentation 0 0
Handler read rnd Documentation 46.4 M 46438968 The number of requests to read a row based on a fixed position. This is high if you are doing a lot of queries that require sorting of the result.

Sort range Documentation 226.3 k 226254 The number of sorts that were done with ranges.
Sort rows Documentation 46.9 M 46931570 The number of sorted rows.
Sort scan Documentation 781 k 780995 The number of sorts that were done by scanning the table.

Table locks immediate Documentation 645.2 k 645150 The number of times that a table lock was acquired immediately.
Table locks waited Documentation 0 0 The number of times that a table lock could not be acquired immediately and a wait was needed. If this is high, and you have performance problems, you should first optimize your queries, and then either split your table or tables or use replication.

Threads cached Documentation 0 0 The number of threads in the thread cache. The cache hit rate can be calculated as Threads_created/Connections. If this value is red you should raise your thread_cache_size.
Threads connected Documentation 2 2 The number of currently open connections.
Threads created Documentation 3.1 k 3148 The number of threads created to handle connections. If Threads_created is big, you may want to increase the thread_cache_size value. (Normally this doesn't give a notable performance improvement if you have a good thread implementation.)
Threads running Documentation 6 6 The number of threads that are not sleeping.
