i dont know if you understand, we do not talk about some % speed diffrence.we talk about
of 68k netsurf.
No we don't, and I've already explained why not.
Its really hard to find a OS4 User that show his speed results.many
OS4 users have a red sight
glass, and never show something that on OS4 look not good.
There are timings available on the public NetSurf OS4 screenshots.
I've already said that NetSurf is faster than any other CSS browser
available for OS4, so I don't see any need for a cover up (even if it
wasn't the fastest, there is no need to cover up any speed figures
which depend as much on the user's network connection as they do on
the OS and hardware)
I only want information, that there is a huge slowdown problem.its
upto you if you try to search for
it, or build a netsurf OS4 SDL version to compare.
I don't believe there is a huge slowdown problem in the rendering
phase, that's a tiny part of the overall process (much more time is
spent on processing and fetching). I could build Framebuffer-SDL for
OS4, but I suspect the speed difference will be minimal, and certainly
nowhere near the 3-5x difference you are quoting.
you can also verify the results if you get same speed values.
I don't dispute the results, just the comparison which is meaningless
It is pointless to discuss this further at this time. Either get some
SDL speeds under scientific test conditions, or do the same with an
OS4 frontend build on 68k, and then report the speed differences or
provide me with a patch to fix them.
You can also set cairo_renderer:0 in Resources/Options on the OS4
build to force it to not use Cairo, if that is your gripe. There is
no discernable speed difference between that and the default mixed
graphics.library/Cairo plotters (full Cairo *is* slower because
clipping takes an extraordinarily long time)
