Profiling

January 27, 2006 3:11 am General

Federico, any of the examples I’ve been posting to my blog really only touch the surface of what’s possible – even with the best tools, you still have to analyse the data to see what’s going on, and I personally have other projects that I need to be spending my time on. FWIW, I’d still prefer not having to recompile my kernel to get this data.

As an exercise, I wrote another script that shows what files are being opened, and started it before GDM [since I’m not too interested in boot time]. You can see the output here, which basically ticks through each second telling me what programs have been started, what files they’re opening, and a count at the end of how many times the file was opened.
