Summary[edit]

Description
English: This compares query performance between equally weighted production slaves serving en.wikipedia.org. Query data is taken via Percona's pt-query-digest, regularly sampling query data via tcpdump and displayed via Ishmael. db1042 = mysql-at-facebook 5.1 r3753; db1043 = mariadb 5.5.30. Lock time and row data fields are empty due to feeding pt-query-digest from tcpdump instead of verbose slow query logs.
