between diffrent CPU and compiler can maybe 20-60% diffrence
but the slowdown of OS4 version is
3-5*.thats very large.You dont want compile netsurf SDL Version to see if your use of
Cairo slow all
If that is what you are trying to achieve, then what you need to do is
compile NetSurf 2.7 Framebuffer-SDL for OS4, using the exact same
compiler with the exact same switches that I used, use a local page
for testing so there are no network variances, exact same window size
etc. If you do your tests under scientific conditions then maybe I
will take notice of the results.
I would still rather receive a PATCH that improves the speed than an
email moaning that it is slow (especially as compared to other CSS
web browsers on the same hardware/OS, it definitely isn't)
Use netsurf on OS4 in 32 bit is maybe faster, because the routines
need no byte swapping.
NetSurf does byteswapping regardless of where it is run, either in the
bitmap conversion functions or when it goes to screen. This is true
even for RISC OS AFAIK. It certainly does not contribute to any 3x
difference in speed.
