[xdebug-general] Re: Profiling a Joomla page -- huge mismatch between xdebug profiling information and actual performance

Hi,

Wincachegrind's reported timings must be multiplied by 10. xDebug 2.0.0 RC4
changed the way timings are reported (µ seconds instead of tenth of µ
seconds), and unfortunately Wincachegrind hasn't been updated for years.

So if you see 1.5 seconds in Wincachegrind, it really is 15 seconds :)

I'm using wincachegrind, currently, but I have a linux system at home
I could use for other clients. How so? Would different data be
reported by different viewers?
