💅 dtestcm(1) — like, the uDAPL connection-timing test, bestie

okay so this is a page from the USER COMMANDS section of the manual, and it's about dtestcm (that's the (1) part, iykyk). Sit down, grab a boba, we're doing uDAPL benchmarking ✨

🌸 NAME 🌸

dtestcm — a simple uDAPL test that measures setup time and connection establish time 🦋

✨ SYNOPSIS ✨

dtestcm [-mwvu] [-P provider] [-b burst size] [-p port id] [-c
connections num] [-d delay] [ -s | -h HOSTNAME ]

like yes it's a mouthful, but she's worth it 💖

🎀 DESCRIPTION 🎀

okay so dtestcm is a simple test that measures setup time and how long it takes to establish one connection on AVG. that's her whole thing. that's the assignment and she ate 🔥

the way that you need at least two instantiations of the test running — no cap, minimum two. one of them acts as the server and the other one is the client. they're giving duo energy, one carries, one receives 💅

the server side of the test, once you invoke it, just listens for connection requests — literally just sitting there, waiting, until it times out or gets killed 💀. and then, upon receipt of a connection request, the connection is established. periodt.

and once all the connections are established, we calc AVG time. that's the moment. the main character moment. 🌈

👑 OPTIONS 👑

one bullet per flag, bestie, no skipping, every single one is here 🫶

• -P=PROVIDER — use PROVIDER to specify the uDAPL interface, using /etc/dat.conf (default ofa-v2-ib0) 🧚
• -h=HOSTNAME — use HOSTNAME to specify the server hostname or IP address (default — none) 🌸
• -b=BURST_SIZE — send BURST_SIZE connection requests at one time (default 100) ✨
• -d=DELAY_TIME — delay for DELAY_TIME seconds before close (default 0) 🎀
• -p=PORT_NUM — use PORT_NUM to established connections (default 45248) 💜
• -c=CONN_NUM — establish CONN_NUM connections (default 1000) 🦋
• -v — verbose output (default off) 🙈
• -m — multi listens. listen on burst size PSP (default off) 👑
• -u — run ud test (default no) ⭐
• -w — wait for CR (default poll) 🌈
• -s — run as server (default — run as server) 💅

🔥 EXAMPLES 🔥

Example one, the server girlie:

dtestcm -P  ofa-v2-ib0 -v -s

Starts a server process with debug verbosity using provider ofa-v2-ib0. she's loud, she's verbose, she's serving 💖

Example two, the client bestie:

dtestcm -P ofa-v2-ib0 -h server1-ib0

Starts a client process, using ofa-v2-ib0 provider to connect to hostname server1-ib0. she's reaching out first, iconic behavior 🫶
