Hallo,
today I thought I should give 0.34 a try. I downloaded and compiled TEST 5, installed it suid on my linux box and then ran my PDX7 patch (www.fbar.mynetcologne.de) with realtime scheduling.
As soon as I started that patch, pd eats up all my cpu resources. I can barley move the mouse to the xterm I started pd from to Ctrl-C it.
Now I wonder why 0.34+test5 has such problems with my patch, I did not have them with the same patch under 0.33.
Any ideas,

i briefly tried 0.34 last week but i (also) noticed it used about 40% percent cpu in dsp off state compared to ca. 12% in 0.33, the same patch.
I just checked, and in 0.34test5, if you just type "./configure" you don't get C optimization... could this explain the problem? Try "./configure --enable-opt" and see if things get better...
When I do that, the testtone patch eats about 4.6% of my processor (a P3 550) and when I don't it's more like 8%. So your patch might have been eating 70% and gone right over the top without optimization...
Since releasing "test5" I've figured out how to get "configure" to do optimization by default, so I hope this problem will go away.

Yes, this indeed helped, thank you. Now I can use 0.34, and you've found another bleeding edge crash test dummy ;-)

Oops, sorry if this is a duplicate, I think I sent the first one out wrong.
I discovered that on 0.34 test5, if you just type "./configure", you don't get teh C optimizations... to get them type "./configure --enable-opt".
I tried both ways and saw 4.5% processor with optimization and 8% without, running the testtone patch on my p3 550.
Soory about that... I've already fixed it for the "real" upcoming release and had forgotten all about it.
