  "message": "go/net/ssh: improve throughput by more than 100x\n\nUse concurrent writes (this is safe for our usage) and use\nReadFromWithConcurrency to extract maximum concurrency from the process.\n\nIncrease the window to 1024 pending reqeuests for a bandwidth-delay\nproduct of 32MiB, sufficient for ~1Gbps at 300ms RTT.\n\nIn practice this improves upload performance from ~13Mbit/s on 15ms RTT\nup to over 1.5Gbit/s, now being limited by the weak network\nimplementation on the small GCP instance I tested this on. Maximum\nperformance with a bigger instance and \u003c1ms RTT was over 5Gbps, becoming\ndisk-limited.\n\nChange-Id: I2f08d2c815fd15794f497ed9dc7a7f8a2e351992\nReviewed-on: https://review.monogon.dev/c/monogon/+/3435\nTested-by: Jenkins CI\nReviewed-by: Tim Windelschmidt \u003ctim@monogon.tech\u003e\n",
