So, I was told PS2 games on OPL via UDPBD slow down less than on OPL via SMB. How can I run it? Also, is the PS2 game compatibility higher on OPL via UDPBD than on OPL via SMB?

If I understand correctly, the current form of what was called UDPBD (UDP Block Device) has been realized in OPL as the more standard NBD (Network Block Device) which is a linux compatible network protocol.
As for how to use it, you would want to go here: https://github.com/ps2homebrew/Open-PS2-Loader
and read the section under "NBD Server" (the server is integrated into OPL). Under that is some recommended clients for your computer.
That said, it seems to say that NBD is currently only supported as a way to populate a PS2 HDD from your computer (add games from a computer to a PS2 Phat HDD so that the games can be played from internal HDD - not streaming over the network).

I didn't say NBD WAS UDPBD, I said it was the current realization of the idea behind UDPBD.I was told in Reddit that NBD isn't UDPBD.

If you really want to go down the rabbit hole of outdated/unsupported stuff - here you go:
I truly hope you find what you are looking for.
- Read comments here: https://github.com/ps2homebrew/Open-PS2-Loader/issues/325
- Only OPL branch that supported UDPBD (tho I don't see any indication that it still does in its current form): https://gitlab.com/ps2max/Open-PS2-Loader
- And here's the MEGA link for all the older/archived versions of OPL generated by the "ps2max" branch: https://mega.nz/folder/Ndwi1bAK#oLWNhH_g-h0p4BoT4c556A
This is not true either.I said it was the current realization of the idea behind UDPBD.
They are two totally different things.What is it, then?
Take, read:

Hi I'm totally new here and facing some issues like others here.
I have a PS2 Slim 90004 with Matrix v1.93 in it
Tried following this video:
but the list of games doesn't show up.
"
Opened '\\.\G:' as Block Device
- read/write
- size = 15726MB / 14998MiB, sector size = 512
Block size changed to 128
Server running on port 48573 (0xbdbd)
UDPBD_CMD_INFO from 192.168.1.10
"
This is only what I get after running the v1.20 1973 build of OPL and games don't show up
Can anyone please help?
Thanks for suggesting but even after trying to reboot both server and ps2 as well, it's of no avail.. Instead it now works when I am using the neutrino with udpbd server...it's much lighter than OPL( given the size of just 8MB of Memory Card). A tutorial for the same is on the same channel of which the video has been linked aboveIn my case, OPL sometimes didn't show games until I exited it and/or closed the UDPBD server and ran the former and/or the latter again.

I didn't do any changes in the matrix 1.93 settings.Did you try with other BD or after disabling Matrix 1.93?
Is Neutrino faster and more compatible than OPL? It seems it's much harder to set than OPL. Can it ran games via UDPBD from an USB device connected to the PC or a nano router, and if so, from the same device where the UDPBD server is (unlike OPL)?
EDIT: I was watching the video you mentioned to be able to run Neutrino via UDPBD but after booting GParted Live and clicking "GParted Live (Default settings)", I have a black screen with a tilt or saying something failed.

Yes, but neutrino has nothing to do with speed as both OPL and neutrino would be using the UDPBD server to share data, however neutrino is much much lighter than OPL (given the 8MB memory) and has does have a better compatibily. It doesn't matter whether the Drive is internal or a USB connected to pc(I, myself, am using the USB), only thing is it should be ex-fat formatted through Linux (GParted-if you are using windows), UDPBD server has been there for nano router as well but I haven't tried it yet.
Check if you have properly made the bootable usb files or not, also many systems don't allow to boot from USBs by default, you can check for your respective system and enable it in BIOS setting as per your system model.
