[linux-audio-user] Softsynth performance

Has anyone done any comparisions in terms of realtime performance of any of the softsynths. I was interested in seeing results of the following or possibley other synths compared: csound pd sfront I was curious how well sfront performs because you can optimise that for your instruments to your processor. It seems rather interesting that the instruments get translated into c code that you then later compile with gcc. I know pd probably has a faster developement time similar to writing something in perl but is the execution performance the same as say sfront or csound? What has better performance for real time stuff csound or sfront? Thanks, Jeremiah
