It's a massive improvement over the CM3, and the only _major_ difference from the Pi 4 is the exposure of the PCIe slot. The Pi 4 actually has the same hardware, but it's hardwired to a single USB 3 chip.

Hi Jeff, I had just finished connecting my Asus GT-AX-11000 to my 10Gb network and put your KZbin on and by happenstance I came across your posting about a problem that I had just worked out. I had just finished connecting my 2.5Gb Asus port to my MikroTic CRS305-1G-4S+IN Switch (Also works with CRS309-1G-8S+IN). The 2.5Gb Asus Port can be used with WLAN or LAN. What makes this work is the SFP+ adapter that is connected to the Switch. I used a Cat 8, RJ45 cable but something less shielded should work. The SFP+ connector that is necessary is Wiitek 10GBase-T SFP+ RJ45 30m CIS (P/N: SFP-10G-T). I learned of this on the SaveTheHome site on KZbin (Comparing 9 Popular SFP+ to 10Gbase-T Adapters at 9’ 15”). Since you showed your MikroTic Switch all you need is the right SFP+ adapter, it works great and now allows my wired network to communicate with some of the faster Wi-Fi connections that are flowing through my GT-AX-11000. Hope this helps.

These cheap expanders seem to be getting more expensive now versus two years ago, when they were like $15 for 1 => 4 expanders when crypto mining was more popular. Even at only 500MB/s, that could likely make network + disk IO (with cheap SATA expansion card like old 3Ware or newer LSI or Marvell controllers/hbas.

You might want to just do "-j" without specifying the amount of threads to use! the kernel scheduler will optimize the branching at every step. even if you have the same amount of threads at you use as a -j argument, it's still faster. -j[] is typically used when you need to guarantee only a certain amount of resources are used

Just a tip: if you want to transfer files between your computer and the pi you don't need to unplug the SD card and mount it on your mac. You can just use the *_scp_* command. The basic syntax is *_scp path/to/file/or/dir/to/copy username@hostname:/path/to/destination_* . This also works the other way round. That's useful for some things, but if you need to do more ssh also supports mounting the remote filesystem using *_sftp_*
