Simple grpc performance tool in Python
./build.shFirst start up the server
./run_server.shthen a corresponding client
./run_client.shTested on i5-8250U CPU (4 cores, 1.60GHZ) with 1000000 messages.
| Compression | Batch size | Result |
|---|---|---|
| Gzip | 100 | 75,000 msg/s |
| Deflate | 100 | 78,000 msg/s |
| NoCompression | 100 | 90,000 msg/s |
| Gzip | 1 | 5,100 msg/s |
| Deflate | 1 | 4,900 msg/s |
| NoCompression | 1 | 4,600 msg/s |
Batching and no compression offers the best throughput when testing locally. This is similar to the results achieved in https://github.com/FranekJemiolo/websockets-performance#example-results. Conclusions are similar, when network connection becomes an issue I would suspect compression would lead to better results.
What is interesting is that out of the box websockets offers almost 3x better performance than gRPC in certain situations.
