✨ NAME ✨

dapl-testcm — a simple uDAPL test that measures setup time and connection establish time, no cap ⏱️💖

---

🌸 SYNOPSIS 🌸

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

like, look at her. iconic. 🎀

💫 DESCRIPTION 💫

okay so dapl-testcm is a simple test — and the whole vibe is: measure setup time, plus how long it takes to establish one connection on AVG. literally the point of the whole thing 🫶

bestie, hear me: you need at least two instantiations of the test running. no solo runs, this is a duo situation 👯‍♀️ one acts as the server, the other the client.

the server side of the test, once invoked, listens for connection requests — and it just keeps doing that until it times out or gets killed 💀. upon receipt of a connection request, the connection is established. and upon the establishment of all the connections, we calc AVG time. math era 🔥

starts a server process with debug verbosity using provider ofa-v2-ib0. main character energy, fr fr 👑

dapl-testcm -P ofa-v2-ib0 -h server1-ib0

starts a client process, using the ofa-v2-ib0 provider to connect to hostname server1-ib0. slay, now they're talking 💬💖
