Help optimize the performance of NAS 314
I had read through some of the posts which "admin" recommend before posting however some are not specific to RN 314. I will try these tweaks from others to see if it help: -turn off Jumbo frames o...
There are indeed some things to speed up a NAS at a software level (defrag, fylesystem repair, freeing some space on the disks, disabling unneeded services...) but performance problems are usually bottlenecks. Why to you want to optimise the performance in the first place ? If you already have decent speeds there is not much you can do.
- Most people experience bottlenecks on their network, a single gigabit link is limited to 120Mbytes/s no matter what you do, and this number assumes a perfect network which is never the case, so expect less.
- The second bottleneck is usually CPU or hard drives. if you have SSH enabled you can check this with the "top" command, if you have idle at 0%, look at which category is used. if that's "us" or "sys" then you CPU is used by applications, if that's "wa" and you already ruled out network, then it is probably the disks.
- Then there is the RAM, usually it is not a problem on NAS. If you have SSH the "free -h" command will give you the information you need. As long as you don't use swap, you won't need to upgrade, no matter what the free category says.
If you already ruled out all that then, check the smart status of your drives, they may have some errors on them.
