  • phpMyAdmin (query profiling)

    for anyone using phpMyAdmin, I just upgraded to 2.11 and they added a query profiling tool which is really handy for optimizing your queries.

    Here's an example output i got from a quick query on a sessions table using innodb on mysql 5

    Profiling
    Status Time
    (initialization) 0.000003
    checking query cache for query 0.000038
    Opening tables 0.000012
    System lock 0.000018
    Table lock 0.000044
    init 0.00002
    optimizing 0.000006
    statistics 0.000015
    preparing 0.000011
    executing 0.000005
    Sending data 0.004121
    end 0.00003
    query end 0.000008
    storing result in query cache 0.000026
    freeing items 0.000016
    closing tables 0.000009
    logging slow query 0.000004

    Showing rows 0 - 29 (~3251 total, Query took 0.0060 sec)

    i can't wait to start tuning my queries with this. it shows me just what's going on and is easy to access.

    just a heads up. hope it helps!

    How do you access this "query profiling tool" exactly?
    I am using phpmyadmin 2.11 and it seems this tool is
    really well hidden.

      After you run a query there is a check box next to "profiling" on the resulting color formatted query they regurgitate back to the screen.
