> Another thing to try might be turning off HTTP/2 as this could be TCP HOL-blocking. Turning off HTTP/2 works very well. Here's how throughput scales with number of concurrent tasks: Concurrent Tasks | HTTP 2 | HTTP 1 -- | -- | -- 1 | 197.9 | 202.01 5 | 252.2 | 666.4 10 | 265.7 | 975.8 20 | 235.7 | 1283.0 > I'm not very familiar with GCS but the S3 API is HTTP1 only. I was able to confirm this does not affect S3: Concurrent Tasks | Time (s) | MB/s -- | -- | -- 1 | 10.9 | 91.8 5 | 2.9 | 344.8 10 | 1.4 | 719.5 20 | 1.3 | 761.1 -- This is an automated message from the Apache Git Service.
