How’s the depth on the rail kit? We now have a small fleet of the 1U2LW-X570/2L2T units, and the fact the rail kit is a few inches too short for full-depth racks continues to irritate the hell out of me.

Maybe I need to know more about the tests, eh? Compiling the kernel, that’s pretty straightfoward.

What is the nature of the Mariadb test? How many queries in flight, how many spindles, how many rows scanned? How complex are the queries? Mariadb seems like the only one that might be capable of a somewhat whole system test, though probably not so much the ethernet IO.

C-Ray, ssl, 7zip are almost pure CPU tests. I’d be pretty surprised if the platform made any difference.

With all those bits hanging off the PCH it’d be great to see some tests of internal bandwidth, identify if there are bottlenecks.

Say you had an A10 GPU in the slot and it was slurping data from elsewhere via 10Gb ethernet, and some other process is beating the heck out of an NVME SSD in the m.2 slot, and a third process is having a strong exchange of views with a collection of SATA SSD configured as an mdraid RAID 0.

Situations like that. Can that CPU to PCH link keep up, or is the system actually not capable of heavy multitasking work?
