RN3220 CPU upgrade -- Negligible effect??
I upgraded the processor of an RN3220 from an i3-3220 3.30GHz, which is dual-core 4-thread CPU, to a Xeon E3-1225 V2 @ 3.20GHz, a quad-core 4-thread CPU as comes in an RN4220 and sysbench shows almo...
OK, I'm not entirely sure what was going on. I upgraded a second one and got way better results. So I swapped the memory between the two and the first one now gave me the improved speed. Just to check, I swapped the memory back, and now they both perform like this:
Test execution summary:
total time: 2.5567s
total number of events: 10000
total time taken by event execution: 20.4385
per-request statistics:
min: 1.02ms
avg: 2.04ms
max: 28.60ms
approx. 95 percentile: 11.02msThreads fairness:
events (avg/stddev): 1250.0000/27.44
execution time (avg/stddev): 2.5548/0.00So, the memory must not have been seated well, even though dmidecode showed both banks properly. Since I swapped out the memory before the CPU, I suspect that the performance shown for the original processor is also bogus.
So I found a video card that would fit and booted to BIOS. The NAS had already identified the CPU and, while you can limit the number of cores enabled, the default was "All". Since I find it hard to believe Netgear would put in a more expensive CPU with such a little improvement in performance, and the specs show there should be significant improvement, I think that maybe sysbench just isn't a good tool to use here. Then again, the Xeon does support VM and that Core i3 doesn't, so maybe that's the reason.
What Video card did you use? , were all drive bays populated? I have one that seems to have been taken out by a power surge, any suggestions would help, Thanks
I used a Zotac GT710 Zone Edition PCIE=X1 (yes X1) card which is a low profile card. It only requires a single slot unless you want the VGA connector. The VGA uses a separate slot but is connected via a cable. But they are hard to come by. It's also available in a X16 form factor, so be sure you get the right one. And be sure you get the low-profile bracket(s).
Zotac also made a fewer older ones that are similar form factor and ought to work. Several companies made GT210 based PCIE-X1 cards. The problem with most is getting the low-profile bracket. But if it's just for troubleshooting, you could go without a bracket.
MSI makes a similar card in a X8 format that I suspect would also work, but I've not tried it.
Thank you, I will try to get one of those, I tried a pcix-4 card that had no pins beyond the connecter - did not work
