Subject:SLOW performance over network
View as plain text  
mysql  Ver 14.12 Distrib 5.0.51a, for debian-linux-gnu (i486) using readline 5.2
Strange, strange problem.
Everything was fine yesterday morning, then all of a sudden any query over the network
takes a REALLY long time to return.  If I log in at the server console, every query is
snappy-fast.  There had been no changes to clients or server when this happened.  All
other networking services on the machine seem to be fine.  Processors are between 0-3%
utilization, disk is at 8% utilization.
Server runs apache as well. There are many php pages on this web server that access the
database, and display the results, all snappy-fast as usual.
I still use the old MySQL Administrator GUI on my windows box.  A simple 'select * from
tablename'  that would return only three records takes just over a minute to return
(although it says '3 records returned in 0.0086 seconds' at the bottom).  I have many ODBC
clients accessing this server as well, they all have slowness problems too.
I'm stumped.  What could possibly be causing this issue?
Thanks for any ideas!
