Re: gRPC Performance

+grpc-io

Unfortunately, I'm not the best person to answer this question. Adding grpc-io, so that someone working on C++ or Java performance can answer this.

Hi Matt,

 

This is Nan from Quantcast. Our team at Quantcast is looking for gPRC performance numbers and we are glad to find this very insightful chart: https://performance-dot-grpc-testing.appspot.com/explore?dashboard=5636470266134528

 

However, we are a bit confused, in throughput QPS charts (both unary and streaming), why Java has much better performance (almost 2x) than C++? We do appreciate if you can give us some hints about this. Thank you!

 

Sincerely,

Nan

Thanks for bringing this to our attention. The numbers look very low for C++ (especially for unary, its way too low). We are investigating..

thanks,

Sree

Hi Sree, 

any updates? we also found that some data is missing: https://performance-dot-grpc-testing.appspot.com/explore?dashboard=5636470266134528

Hi Nan,

The infrastructure behind those dashboards has fallen out of maintenance. We have a very comprehensive internal set of dashboards. I see no reason why they can't be made public, to replace those old ones. I will look into this further.

Best,

Noah
