November 23, 201015 yr I have built a new unRAID server using the following components, and the read/write speed between the server and Vista SP1 is very low, lower than I believe it should be after reading the config and troubleshooting guides. I'm looking for suggestions to what to try next. System: ASUS M4A785T-M AMD Athlon II X3 445 Rana 3.1 Ghz 4Gig RAM (Corsair, and passed Memtest) 5x Seagate Barracuda 7200.12 ST31000528AS 1TB 7200 RPM I am running unRAID Server 4.6-rc2 (I know this is the 4.5 forum but I couldn't find a 4.6 forum). I have a Pro license. I have 4 of the devices mounted, and have not added the parity drive yet, will do it once I transfer all my files. I also do not have a cache disk. Write speed - 11.0MB/sec Read speed - 8.8MB/sec Ping to the server is <1ms Network is handled by a LinkSys SR224 Switch I have tried both direct disk and shared folder writes/reads - I get the same performance.
November 23, 201015 yr There is currently no unRAID 4.6 (and there isn't likely to ever be one). I'll assume you are running 4.5.6 Your speeds are perfectly normal for you network - which is a 10/100 network. If you want faster speeds, you'll need a fully gigabit network, which means a new switch/router, cat5e or better cables, and a gigabit LAN port on your client computer. Your unRAID server already has it, so at least you are set there. Do you actually need a 24 port switch? If not, then I would start by replacing it with a small gigabit switch. This is what I use: TRENDnet TEG-S5g If you do actually need a 24 port switch but don't want to spend a ton of money, you can keep using your current one for all your devices that don't need gigabit LAN speeds. Then buy the above 5 port switch (or something similar) and use it to hook up your unRAID server, client computer, and any other device on which you want fast transfer speeds. Use the 5th port to hook it into the 24 port switch to connect to the rest of your network (for example, your internet connection could still come through the 24 port switch).
November 23, 201015 yr There is currently no unRAID 4.6 (and there isn't likely to ever be one). I'll assume you are running 4.5.6. Check the announcements forum, there is a 4.6rc2 out. It fixes some kernel oops errors and a few other things. After 4.6 is out there will probably be a 4.6 forum.
November 23, 201015 yr There is currently no unRAID 4.6 (and there isn't likely to ever be one). I'll assume you are running 4.5.6 Actually there is... and we're currently on 4.6-release candidate2. You must have missed the announcements of 4.5.7, 4.5.8. and 4.6-rc1. (4.5.7 and 4.5.8 were removed from the downloads area as they both had bugs that affected some users) Joe L.
November 23, 201015 yr What Raj is saying is that on a 100 Mbps network the theoretical max transfer speed you could get is 100 Mbps which is 12.5 MB/s. So getting 11 MB/s writes is achieving 88% of max theoretical throughput; which is pretty good for a real world scenario. For faster speeds you will need to upgrade your hardware to support Gigabit as Raj suggested.
November 23, 201015 yr Author Thank you all, I clearly didn't understand the 10/100 concept. I went and grabbed a cheap 5 port GigE switch and my read speed is 90MB/sec and write (without parity enabled) is 70MB/s. Thank goodness I had cat5e installed when I had the house built 8 years ago.
November 24, 201015 yr Oh snap! I travel for 10 days and look at all I miss! Hah, you better get busy catching up on forum posts! And hope you had a good trip too
November 24, 201015 yr What do you think I've been doing all day? Work be damned My trip was great, thanks. Only suffered one concussion, so that's a plus. Also got to sleep on a three story bus.
