Nathan,
The profiling I included proved that was not the case.
Mysql run the query and return the single column single row result in under
1 second but PHP's mysql-query waited much longer than that to return. If
it was a big result set I could see some slow down in parsing the results
into memory but this wasn't the case. Updates/Deletes have similar random
timing issues , and using mysql profiling, I can see its not transit or
lock or clean up time from mysql - php , it is purely inside the php
mysql functions the slow down seems to be occurs , but I can dive into
those as they are compiled modules not userland functions.

I enabled profile in mysql to determine why an update took 20seconds. As
you can see MySQL reported no where near that amount of duration took
place.
Is there any way I can dig into php and determine why mysql client libs
are
so slow (this is not using mysqlnd but mysql-client-libs on CentOS using
5.3.2)
