Increase the default HTTP/2 stream window from 64KB (65535) to 4MB (4194304) and the default local connection window to 32MB (33554432). The default 64KB window limits throughput on high-latency connections to window_size / RTT. With a 250ms RTT, throughput is limited to 256KB/s. The new defaults improve throughput to 16MB/s (128Mbps) for the stream window and 128MB/s (1Gbps) for the connection window.
