Hmmm... I compiled [bob~] myself with MinGW and pd-lib-builder and I noticed two things:
- the CPU rise is gone
- it needs only half the CPU. I put 20 [bob~] objects in a switched subpatch and measured the CPU load. The DLL which comes with the Windows binaries needs 15%, while my own DLL needs only 7%! That's quite a deal...

PS: I attached the DLL in case you wanna try it yourself.

Hi Miller,
feeding audio into [bob~] and then going to zero will increase the CPU load by ca. 6%. Clearing the filter or adding a tiny amount of noise brings the CPU load back to its usual level immediately, so I guess it's a problem with denormals. My Pd load meter won't really show the increase, but it's clearly visibly on Process Explorer.
See my attached patch. Tried with Pd 0.47.1, Lenovo Thinkpad L440, Windows 7.
