Oryx 2 recommenadtion || increase Throughput

New Contributor

Hi,

 

We wanted to increase the Throughput of the oryx server layer by using the sample rate(LSH) value 0.3 . Currently our configuration have the value of sample rate 1.0. Will it affect the recommendation of the users.

Will it affect recommendations? yes. However, it doesn't affect the results much until you turn the LSH value down a lot. For example, you may find that 0.1 still yields good recommendations.

 

With 1.7M items however, you should find it's already pretty fast. See http://oryx.io/docs/performance.html . Even with 250 latent features, at LSH=0.3, you could probably serve ~100qps on one modern server with latency ~15ms.
