Do you have access to an ARM machine? If not, I could probably get one online with ssh access, if that's useful.
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)
