I've mailed Joe White with the question if he can patch the code for
libpd and check performance on ARM.
apropos performance:
on my i5 650 @ 3.2GHz, running debian
and trying to osc-delay-perfotest.pd (with only 400 osc-delay
abstractions, as 500 would max out the CPU in "new double" mode) i
get:
original : 28%
debian : 31%
new single: 64%
new double: 86%
the "new" versions are Pd-0.43.1-test4 with only the
PD_FLOAT_PRECISION
set to 32 resp. 64.
the "original" version is a 0.43.1-test2, where i cannot recall any
special optimization flags.
the "debian" version is a 0.43.0 with most optimization turned OFF (as
is debian policy)
Hey IOhannes,
Could you write up a quick wiki page on how to do this performance
testing? I never remember a good setup.
