BW_MEM_RD(8)

💖 NAME 💖

bw_mem_rd — the girl whose whole job is timing how fast your memory reads (and yes, overhead is included, no we are not subtracting it, bestie)

✨ SYNOPSIS ✨

bw_mem_rd size

🦋 DESCRIPTION 🦋

Okay so here's the tea. bw_mem_rd grabs the amount of memory you asked for, zeros it all out, and then times the reading of that memory as a whole series of integer loads and adds. Like, every single four byte integer gets loaded and added to an accumulator. That's the whole vibe. That's the benchmark. 👑

The size spec? It can end with `k` or `m` and that means kilobytes (* 1024) or megabytes (* 1024 * 1024) respectively. slay, units.

🌸 OUTPUT 🌸

The output format is "%0.2f %.2f\n", megabytes, megabytes_per_second, i.e.,

8.00 25.33

no cap, that's literally it.

💅 MEMORY UTILIZATION 💅

This benchmark should move approximately the reported amount of memory. periodt.
