GC should not be an issue. Every 15 sec or so I make a call to (HCL:GC-GENERATION T). And yes, I am using Multi-media subsystem (MMIO). I can open the incoming A/D and request a sample rate of 8 kHz, even though it is happening physically at 48 kHz. There is nothing in the signal above 3 kHz. So, no matter how sloppily M$ pulls off that sample rate conversion, I’ll be okay. (That’s another reason I hesitate to use a Mac here. I don’t believe the Mac will accommodate the fake 8 kHz sample rate. The Windows machine also hooks up to the plethora of RS-232 Serial I/O ports needed by other equipment and software. Yes, EE’s seem to be heavily wedded to Windows PC’s and Serial I/O - now done with USB interfaces.) After this experience, I’m finding that in many ways the M1 iMac and the Windows/11 AMD Ryzen 5 5600G with Radeon Graphics at 3.9 GHz, are both remarkably the same effective compute speed. > On Jan 17, 2025, at 14:36, Toomas Altosaar (as toomas dot altosaar at gmail dot com) <[email protected]> wrote: > > Garbage collection came to mind as well: make a substantial amount of garbage, then time how long (gc) takes to run (or whatever a full gc is called in LW).
