September 16, 20169 yr A little advice on i3-6100 vs E3-1225 v5 vs E5-2670 on a <$500 budget is sought. My D525 is fairly slow on file transfers on v 6.1.9 and unable to take advantage of v6.2 dual parity. I was hoping to replace it and my windows gaming rig with a $1,200 rig (passmark 13467) as outlined https://lime-technology.com/forum/index.php?topic=45735.msg441490#msg441490 however life is not currently obliging (newborn). Which CPU should I use? I want to run Dual Parity, a single Ubuntu OS (dual thread passthrough), and the Crashplan Docker. I also want to have faster SSD Cache writes (currently at 35 MB/S) and re-use my Desktop Class Case. Note that this case is installed in a closet with minimal airflow… will any of these CPUs have heat issues? Current Mobo/CPU: Supermicro D525. No ECC Ram. 2/4 @ 1.8 Ghz. 13W. IPMI.

September 16, 20169 yr The E5-2670s that are going for about $70 on ebay are v1. They will not work with the supermicro board you listed (SUPERMICRO MBD-X10SRL-F Server Motherboard LGA 2011 R3)
September 16, 20169 yr The Core i3-6100 is a 2 core processor with hyperthreading. The Xeon E3-1225 v5 is a four core processor which, as you noted, has a higher passmark score. If you want to do anything serious in the VM then I'd go with the Xeon. Actually, if you want to do anything serious with VMs I'd try to scrape together the extra $70 for the E3-1245 v5 which would get you 4 cores with hyperthreading and over 10,000 passmarks. If that doesn't work, though, then I'd rather be passing real cores into the VM than hyperthreaded cores.
September 19, 20169 yr Author Looks like the current hardware will JUST BARELY keep up in the 6.2 Dual Parity world. My upgrade now goes to a lower priority: Machine Consolidation (do away with Windows Gaming rig and Work Ubuntu Rig) and faster writes to Cache... Reminder that the Atom D525 is a 1.8 Ghz Dual Core with Hyperthreading and a max of 13 Watt with a measly 700 passmark. Write Speed Test Write speed to the Cached Share, all other hardware and test file the same (4 GB ISO File) V5 near 100 MB/s V6.1.9 max of 40 MB/s V2.0 57 MB/s v6.2 Write speeds are still not as fast as v5, however it is nearly 40% quicker than v 6.1.9! The low Cache write speeds have been my biggest complaint with v6, however the benefits far outweigh this obstacle. Parity Check and Build Times Single Disk Parity Check: 10 hours, 4 minutes @ 110 MB/s Dual Disk Parity Build: 17 hours, 46 minutes. CPU at 22-48% use Dual Disk Parity Check: 15 hours, 33 minutes @ 71 MB/s. CPU 2 threads at 100%, 2 threads at 40% Dual Parity check takes nearly 50% longer than single Parity File Read during parity Check One use case of this server is to store Children’s movies as unconverted ISO for playback in the home (mix of DVD and Bluray, all purchased and stored in the crawl). v 6.2 Single Parity – DVDs play with no problem. 1080p files stutter for a few frames every 8 minutes v 6.2 Dual Parity– All movies fail playback after 3-5 seconds. MP3s fail to playback after a few songs. Unable to open RAW image files for editing File Copy during parity Check Note that I do NOT copy files (to the Cache) during parity checks normally, however mover is suspended during parity checks so in theory this should be ok v 6.2 Single Parity – 42 MB/S v 6.2 Dual Parity– 34 MB/s My choices with 6.2 are to choose single parity for read access during parity checks and forgo read access for single parity use, or know the server cannot be used during the monthly check. I think I can live with the kids not having movies and my having to work with a local copy until 4pm on the first day of each month.
September 28, 20169 yr Re do your tunables. Some are getting numbers better than 6.19 with the new scripts and 6.2 with dual parity.
September 28, 20169 yr Author Thanks Nightanole... I had all my excitement over in the 6.2 thread! A few more goodies Write speed performance Boost - D525 Cache Drive: Samsung 850 Pro, 256 GB Max copy speed (pre-tweak) is 57 MB/s during idle & 42 MB/s during a parity check AFTER running [squid's Modified] Pauven's Disk Tuneables script The following was all done on my Windows 10 machine Regedit / (DWORD value) systemCurrentControlSet/Services/lanmanworkstation/parameters/ Create the DWORD DisableBandwidthThrottling and set to 1 gpedit.msc / Computer Configuration/Administrative Templates/Network/QoS Packet Scheduler/Limit reservable bandwidth. Edit, Enable, change 80 to 0 Settings/Updates&Security/Advanced Options/Choose how updates are delivered/Turn OFF deliveries of updates to other computers CMD as administrator (default is 'normal')/ Netsh interface tcp set global autotuning=disabled CMD as administrator (default is 'enabled')/ Netsh interface tcp set global rss=disabled Programs&Features/ uncheck Remote Differential Compression Ethernet Adapter / uncheck IPV6 Ethernet Adapter Properties / Set Speed & Duplex from Autonegotiate to 1.0 GBps Full Duplex (note that I have a managed switch) Disable Unused Network Adapters And the results after rebooting the Windows 10 machine? File copies DURING a dual parity check using TeraCopy are now at 45, and 64 otherwise. File copies DURING a dual parity check using Windows Explorer are now at 78, and 98 otherwise. Speakeasy jumped from 22 down to 37 down. Using Explorer I am now up to full copy speed... Using TeraCopy's built in file integrity check I loose a little max speed, but this is still double my best write speed scenario under v 6.1.9 (and untweaked Windows)
