SDS Posted March 9, 2007 Share Posted March 9, 2007 In trying to determine if our server is I/O bound, but there is no "wait" percentage listed under my CPU stats like some people have alluded to. Does anyone know how to determine how I/O bound we are? Normally when we are loaded heavily, the CPU is at 75% and higher, so maybe I/O isn't an issue (I had read if the CPU load is low, but the "wait" is high - then it is I/O). We are running FreeBSD FWIW. Link to comment Share on other sites More sharing options...

We are running FreeBSD FWIW. Hi Scott, There is no easy answer without knowing more info. Here are a few things that come to mind, in no particular order since that is how my mind works: 1. What version of FreeBSD are you using? 2. Are you running the generic kernel or have you optimized it? 3. Do you know if mysql has been tuned for performance? 4. What type of hardware are you running things on? Newer, older? Link to comment Share on other sites More sharing options...
