Hello Ronan, Whenever I'm debugging performance issues on Linux I have a window open with the site that's misbehaving, and another window open with top running I have the top refresh rate set to every half a second, and then I hit the page.
If the problem is with CF or the CFML code, you can see the CF java processes spike the CPU while the page is loading. If the problem is with the database, you can see the database processes spike. Have you watched your processes in this manner and noticed any kind of spiking like this?
