For the less visually-inclined, here's a tl;dr as well as a link to the blog post for this video[1]. tl;dr — A Rosewill 2.5 Gbps PCIe 1x card worked with the Pi Compute Module 4 + IO Board, but it required a kernel recompile to install the proper drivers for the Realtek chip (the Realtek website driver download didn't compile on the 64-bit Pi OS beta (though I didn't try _too_ hard). Without overclock or Jumbo Frames, I got around 1.9 Gbps. With Jumbo frames, I got 2.48 Gbps, and with normal MTU and a 2.147 GHz overclock (default clock is 1.5 GHz), I got 2.33 Gbps.
