[fluid-dev] FS 1.1.2 alpha performance

[Bernd Casper]

Hi David,

 

I've tested FS 1.1.2 alpha, latest changes, in a jOrgan real-time scenario.

 

I regret to have bad news. The performance of FS 1.1.2 alpha in relation to 1.1.1 release has suffered strongly by the latest changes. The latency is increased that much, that I cannot run my bigger instruments anymore. Those organs were running near perfectly with FS 1.1.1 release. With FS 1.1.1 release I had a near-zero latency while using the full organ with many FS instances. Now the system resources max out ca. 50%-70% earlier, and if I play a big chord with full organ, the system hangs and I've to restart the machine.

 

I've tested anything with the parametres, both kernels and polyphony settings - even reducing polyphony to 128 and channels to 16 gave no improvement.

 

Sven has confirmed, he compiled no debug version.

 

Regards

Bernd.
