✨ QUEUELAT(8) ✨

okay bestie, welcome to queuelat — it's a System Manager's Manual page and it's giving "queue latency test program" energy 💅 no cap

🌸 NAME 🌸

queuelat — Queue latency test program 🦋

🎀 SYNOPSIS 🎀

queuelat [-c|--cycles N] [-f|--freq F] [-h|--help] [-m|--max-len LEN]
[-p|--packets F] [-q|--queue-len N] [-t|--timeout TIME]

💖 DESCRIPTION 💖

okay so queuelat simulates a network queue and it's literally checking for latency violations in packet processing 🫶 like it's out here vibe-checking your packets to see if any of them are taking too long, and if they are? it says something. iconic behaviour fr fr 😭

✨ OPTIONS ✨

a summary of options is included below, and yes we're doing all of them, no skipping 💜

• -c, --cycles=N — Estimated number of cycles it takes to process one packet. this value should come from the envisioned packet forwarding application being simulated 👑 so like, don't just make it up, get it from the actual thing you're pretending to be.
• -f, --freq=F — TSC frequency in MHz 🌈
• -h, --help — Show help 🙈 (it shows help. that's the whole thing. slay.)
• -m, --max-len=N — Maximum allowed latency, in nanoseconds. If latency to process any packet exceeds this value, the program quits, writing a message to the trace buffer 💀 so yeah — cross this line and it's over, bestie, and it leaves a lil note in the trace buffer on the way out.
• -p, --packets=F — Million packets per second that arrive for processing 🔥 (yes, million. it's a lot. it's giving main character throughput.)
• -q, --queue-len=N — Minimum queue length to print in the trace ⭐
• -t, --timeout=TIME — Timeout in seconds to quit the program 🎀
