Please describe.**\r\n\r\nhttps://gist.github.com/szmarczak/4a764b3d00ae217267c9d79caafd4082\r\n\r\nIt is now possible to set the window size on the session & its streams. By default, it's **64KB** which is **too small**. When connecting to really remote servers, there can be even **250ms** latency. That is **4** packets per second! What a fantastic speed of **256KB/s**.\r\n\r\nOkay, you might want to connect to a close server, assume **20ms** ping. That's just **50** packets per second.\r\nMeaning: 50 * 16 = **3200KB/s**.\r\n\r\n**Describe the solution you'd like**\r\n\r\nThere are many 1Gbps connections out there. Let's make the session window size 128MB and the stream window size at least 16MB. ***Okay, that's overkill, see my comment ~~above~~ below.***\r\n\r\nThis way, with 250ms latency the speed will be 64MB/s (512Mbps).\r\n\r\n**Describe alternatives you've considered**\r\n\r\nNone.\r\n\r\n/cc @kanongil @Rantoledo @CrucialDrew @fungiboletus @sindresorhus\r\n","author":{"url":"https://github.com/szmarczak","@type":"Person","name":"szmarczak"},"datePublished":"2021-04-27T02:22:36Z","url":"https://github.com/nodejs/node/issues/38426"}
