Update gear to improve stats? Old vs new Mac.

[waban]

Good question. I had to replace my old iMac in late 2019. Here's my experience with a new iMac (SSD internal),
- Catalina OS,
- modest Fios (82 down, 29 up)
- 2009 Apogee ONE interface (USB 1.1)

→ latency was 10.2ms
I dropped the Frame Rate to 1 and now see latency of 7.8
jitter bounces around, going between .5 -.7, then dropping way down, ...
processor use is usually in 4-6% (w/o video; a little more, not much, with video)

Is this better than what you are seeing with the old Mac Pro + firewire?

Hope this helps.

I just posted a parallel question about updating from USB to thunderbolt.
