just moved and trying to configure best way to do my channels server. Im going to load it on my rpi4 now, is there a limit of how many recordings can occur simultaneously?
As long as your hardware allows for it, there is no limit. If Channels can open a stream to record, it will try to record. Of course, if you try to do too much, the system may suffer because it doesn't have the disk IO or network bandwidth to keep up ...
@clarkr32, still figuring this out myself too. 
Using a USB3.0 HDD, have run into buffer full issues when recording 3 OTA, one TVE when ComSkip is running on a long 2hr+ OTA show. Turning off ComSkip did seem to keep up, but watching a recording while all this goes on, was a little buggy when FF/RW still. OTA uses more resources than TVE.
I've moved to a M.2 SSD and testing with ComSkip back on. So far performance while viewing recordings is very good and ComSkip with 1 core selected seems to perform well without causing buffer full issues. Only have a week+ on this setup, so not fully safe to recommend.
What I'm trying to get to is a baseline of recording a mix of up to 5 records mostly OTA recordings with ComSkip with 1cpu enabled while viewing one recording. So my mix would be 3 OTA and 2 TVE typical mix. I have a bunch of recordings tonight to see if this is capable.
Let us know how your testing goes so we can compare notes. Thanks.

As a data point I have had several times three TVE and one OTA plus ComSkip running with 1 core and had no problems.

Very happy with a Pi running with a M.2 Sata SSD. Was recording tonight 3 OTA, 2 TVE, ComSkip was running, while also playing two recordings. FF/RW with no issues. With the USB3 HDD with ComSkip enabled, FF/RW would be buggy. Periodic scans of the CPU load avg. tonight were below 3.7. On an HDD with ComSkip running, it was typically going past 4.0.
I was thinking of going back to a Mac/PC to run Channels, but going with a SSD seems to be good enough for my needs. Still need more run time; but compared to a Pi with an HDD, seems address the performance issues I was running into.

where do you get a m.2 sata ssd to connect to RPI?
This is usually an rpi case. The m.2 ends up being attached over usb 3.
Wpuld a hdd be ok for 1-2 streams on rpi over same network inhiise as server?
@clarkr32, I'm still running the Argon ONE M.2 case with a Western Digital 2TB WD Blue 3D NAND Internal PC SSD - SATA III 6 Gb/s, M.2 2280, Up to 560 MB/s - WDS200T2B0B. Case price went up slightly but the 2tb SSD price went down. Did not like the prices then, but it's worth it. It's been very stable and I'm running it on 32bit OS still too. I have not run into any issues with this combo, hence why I have not done an OS upgrade yet.
If you are running 1-2streams, this would be an overkill; but for me, it's been a set it and forget it since going with this combo.
