Changes between Initial Version and Version 1 of Ticket #56, comment 30

initial	v1
1	1	* r17075 adds GLX to Xvfb command line, not sure if that makes any difference. There are other switches that may impact performance: {{{+iglx}}} / {{{-iglx}}}, etc.
	2	* r17080 removes old modes so we don't end up with thousands of modes (which could cause problems with some applications - known to cause crashes with some gnome applications for example), currently set to keep a maximum of 32 resolutions, for testing this can be changed using the env var {{{XPRA_RANDR_MAX_NEW_MODES=VALUE}}}
2	3	* when comparing the performance of Xvfb vs Xdummy, make sure that you don't use virtualgl unless you also intend to use virtualgl in production
3	4	* x11perf may not show much difference between the two (see [/attachment/wiki/Xdummy/Xvfb-vs-Xorg-x11perf.txt]), but other tests might
	5
	6	Note: rather than editing the {{{xvfb=}}} option, you can just build with {{{--without-Xdummy}}} (easier)
