comment why when i use tracert in powershell,it doesn't return complete reponse?
@stackprogramer oh, I see, it's one of those networks. I am not familiar with psiphon, but according to their docs, you should be able to use traceroute in "VPN" mode which is establishing an L2TP tunnel. If it does not work either, try a different VPN tunnel solution.

Glad to hear it was as easy as changing a BIOS setup setting.

comment Poor performance with Linux software raid-10
I did note. The vast difference in performance might be due to one of two circumstances: 1. when using O_DIRECT the CPU is not sent into C3+ sleep or 2. it is sent into C3+, but it does not matter as much due to the significantly simplified processing when using O_DIRECT (just point to a zeroed memory area and issue a DMA write request). Try tweaking PM to ensure the CPU is not going to sleep and re-run the benchmarks. Refer to your distro's documentation on how to do that - mostly this will be the intel_idle.max_cstate=0 kernel bootline parameter, but YMMV.

You might want to use PowerTOP to see if your CPU's C-states are switched too often above C1 under write load. If they are, you should change that and re-run your benchmarks.

Your dd oflag=direct observations might be due to power management issues. Could you check?

@nathan it looks like your use case is different than the one described here. I'd suggest opening a new question with more details.
