LAT_FIFO(8)

💖 LAT_FIFO(8) — the FIFO benchmark, bestie edition 💖

okay so welcome to LMBENCH's little corner of chaos, and today's main character is lat_fifo. pull up a chair, grab a boba, we're measuring latencies 🫶

✨ NAME ✨

lat_fifo — the FIFO benchmark, no cap 🎀

🌸 SYNOPSIS 🌸

lat_ctx [ -P <parallelism> ] [ -W <warmups> ] [ -N <repetitions> ]

not me pointing out that the synopsis literally says lat_ctx — that's what the page says, so that's what we're writing down, fr fr. copying it exactly, character for character, that's the vibe 💅

🦋 DESCRIPTION 🦋

lat_fifo is a client/server program that measures interprocess communication latencies. the way it works is honestly iconic: the benchmark passes a message back and forth between the two processes, and this sort of benchmark is frequently referred to as a ``hot potato'' benchmark 🥔🔥 like, pass it, catch it, pass it back, nobody gets to rest.

no other work is done in the processes. none. zero. the message is just vibing back and forth.

and the message gets passed back and forth using FIFOs ✨ that's the whole bit, that's the flex, periodt.
