[go-nuts] Assembler, ABI0 frame & stack growth

Hi Gophers, I am experimenting with assembler, ABI0 and stuff. While I was learning the ABI0 frame structure from disassembled code, I noticed that the stack check happens before subtracting from RSP (I'm on arm64, but the same applies to SP on amd64, I mean the hardware register ofc). Then,

Hey! May I ask, what would be the practical usage of 500x 1MB buffers? What kind of problem are you solving? Best, -W niedziela, 5 marca 2023 o 22:13:57 UTC+1 Kursk napisał(a): > Oh, interesting enough this performance degradation shows only in some > Linux boxes (heavily optimised) from a LA

Re: [go-nuts] HTTP client - streaming POST body?

Hello, I think this code example rather streams back the response the server sent from its POST handler and it is not exactly what the OP requested ;) (not to mention that the typical result of a POST is an immediate redirect, possibly without body at all). I believe what Jim needs is construct
