October 23, 200916 yr In the last couple of days I noticed that transfers to the server seem to have slowed down. Yesterday they were around 12-15 MB/s, today I am consistently in 10 MB/s territory or slightly under that. These are writes to share using the cache drive. I checked the cache share, and the files are actually been written to the cache drive, can't figure out why it would be so slow. Is 10 MB/s OK using a cache drive (I think not, I can achieve that speed without a cache drive)? While transferring, i see that shfs is taking 20 to 50% of CPU, that does not seem right either. Than again, I do not know linux much, which is probably the source of my problem. Any help much appreciated. Luca
October 24, 200916 yr Author Which unRaid version are you running? Hi, this is a new build, ver 4.5beta6. I posted a thread with all the details here: http://lime-technology.com/forum/index.php?topic=4479.0
October 24, 200916 yr Author I have figured it out. It turns out that this issue had nothing to do with unRAID. A few days ago I replaced the nic on my computer, and the new nic must have gotten stuck on a 100 Mb/s speed (though the link speed was set to "Auto"). I forced the link speed to 1G and I am back to ~30MB/s uploads. Sorry for wasting everyone's time. Luca

You might have a cable or LAN connection that is marginal. Type ifconfig eth0 and look for errors, overruns, etc. You might want to try a different cat5e or cat6 cable if the problem continues. You should not have to force a speed. Joe L.

Yes, I didn't mean to leave it at that. I guess I was happy to have found the source of my problem. I since replaced the cable from the switch (Netgear GS108) to my PC. I reset the link speed to auto, and it was negotiated at 1G. This Netgear switch handles a lot of traffic, would you consider replacing it with something better?
