Oryx 2 recommenadtion || increase Throughput

[#1]

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.

Total Unique Item count:1.7 lakh

Total Unique user count:16.8 Million

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.
