ten gigabit networking I mean think about it transferring files around to remote pcs at speeds upwards of one gigabyte per second that's a thousand megabytes per second well today we're not only going to do it we are going to give you some tips and tricks that will hopefully help you out when the time comes to move to ten gigabit yourself whether it's at work or at home and on the subject of work I thought to myself hey how about clearing some space on my desk at work by building a PC under the desk Wow drop a like on the video if you're amped to see my upcoming desk PC build blog the mastercase 5 by Coolermaster gives you the freedom to truly make your mid-tower pc case your own with a variety of modular parts and accessories click on the link in the video description to learn more you know I still remember how mind-blowing it was like the first time that I saw something transfer over my network it 60 to 70 megabytes per second with the on-board Gigabit LAN port on some enforce board that I had then shortly afterward my mind was blown again when the PCI bus bottleneck was removed and thanks to onboard PCI Express gigabit networking I could transfer files thanks to my trusty Dimond Max 9 120 gig raid 0 boot drive and over a hundred megabytes per second Wow then for the last 10 years well it says no time has pretty much been standing still neat shirt the enterprise space is getting 40 gigabit and 100 gigabit links but it really feels like about a decade ago the entire industry had a meeting and decided that now gigabit is good enough for consumers and small businesses and let's just leave it at that well I say no more we are using and I'm using this term fairly loosely here affordable hardware to go 10 gig at the office today it begins with the Nix that is to say network interface cards will be using Intel X 540 T twos with the only difference between it and the t1 being that it has two ports instead of well one and while any 10 gigabit card will knock the socks off of a gigabit one we chose these for two reasons one their Intel which is basically the industry standard for prosumer network cards not to mention our testing with them is gone very well and 2 because they're both somewhat affordable at 300 bucks a pop on eBay although I got some of mine for cheaper and available in an rj45 equipped variant this is important because we wanted to use Ethernet cables rather than the expensive SFP+ connectors and direct-attached copper cables that we were using in our previous 10 gigabit setup the reason for that is that while that configuration worked well for us before starting out with PCs attached daisy-chaining to each other actually then moving up to using the backbone links on a 48 part Netgear GS 752 TX s which it doesn't play nicely with running cabling through the walls definitely desirable for an office space and it's not scalable and if we want to run more pcs on 10 gig at a time we need a 10 gig switch with more ports and pretty much the switch right now if you don't want to spend an absolute fortune and you know then you might as well get sfp+ gear is the XS 7 12 T 12 port or it's a port little brother from Netgear and those use rj45 connectors all right so it's simple right plug into the Ethernet cables and bippity-boppity-boo your transferring files at a thousand megabytes per second right actually not quite first you'll need to make sure that you're using cat 6a cables if you want reliable data transfer over a reasonable distance and second and you may not have consider this but 10 gigabit is so fast that it exceeds the 6th gigabit per second limit of third-generation SATA so even if you have a wicked fast SSD drive you'll be limited to speeds in the neighborhood of 500 550 megabytes per second and while PCI Express SSDs that overcome this bottleneck do exist I stole our Intel 750 series and put it in my personal rig so I ended up using other solution I've got our 24 SSD storage server on one end the one that we built in this video here and I've got a test bench with that 128 gigabyte kit of Dominator Platinum ddr4 from Corsair on the other end with a free and easy to use utility called soft perfect Ram disk used to treat that round like a hard drive so with such fast storage on either end it's much easier to evaluate the performance of the actual network link which frankly didn't go so hot on the first kick at the county I don't know who these people getting perfect 10 gig performance out of the box are or how many horseshoes they had to put up their butts to make them so damn lucky but I was seeing this weird cap at around 300 to 350 megabytes per second now to be clear that is still a significant improvement and already well worth the upgrade for our purposes but I wanted more den and I paid for more and thanks to an amazing series of posts on thus innovate blog which you should definitely check out we can link them below the video I was able to do much better than that mostly so the first tip from them was this great tool called NTT TCP that has a command-line interface so not the friendliest thing but that they simplified by basically showing you where to plug in the program install path and machine IP addresses and boom it's off to the races so this tool revealed that my two machines were capable of more than one gigabyte per second performance between them so what gives well time to dig into the event settings to see if there's anything that we can tweak I started by enabling jumbo packets on all clients involved in the transfer and on my network switch side note here it doesn't seem to matter if the values don't match up exactly as long as your switch is set to something higher than your NICs so this means that now effectively the data packets sent back and forth are bigger which is better for a high speed transfer of large files next I tweaked receive side scaling a feature that leverages more CPU cores for network transfers and I set it to match the settings with my number of logical processors on my pcs so 16 on my 59 60 X test bench 8 on my 6700 K test bench and 16 on my Xeon server and finally I increased the size of both the send and receive buffers to their maximum this increases memory usage but can yield extra performance so then what did I get well performance wise over the original numbers in ntt TCP not much but my real-world transfers were much higher in fact more higher than they should have been but I'm not gonna complain and I was seeing sustained speeds of over double my original transfer rates with that said not all is necessarily rosy and for whatever reason maybe some of you sharp people out there can go and contribute your comments below some transfers are faster or slower than others so I ended up actually putting together two test benches with brand spanking new installations of Windows 10 and Windows Server 2012 r2 just for the sake of trying to eliminate as many variables as possible I was still running into weirdness where one machine with a particular OS would saturate the connection writing to the Wanek SSD server but then be capable of half or 60% of that speed when reading from it and then another would saturate on reads and then limp along writes I mean that's the one you're looking at here by the way but as snake-bitten as I seem to be when it comes to networking stuff limping along in this case is still 500 plus megabytes per second so I guess I'll just have to deal with my 34 gigabyte file transferring a little slower than it otherwise would overall very happy with the results and speaking of being happy with the results Squarespace if you were thinking to yourself gee I'd like to build myself a website but I sure don't want to be unhappy
