Running an RT-N16 with Toastman's 7497.1 VPN VLAN build with a 1tb EXT3 formatted USB drive.
The problem is that the longer the router is up the slower the USB drive performance becomes. For example yesterday I wanted to watch a video off the USB drive so I opened it from my laptop using VLC. The video played maybe 10 seconds and then stuttered to the point that it was unwatchable. I tried to copy the file (2gb) over wifi (reporting 144mbps connection speed) and Win7 Pro x64 was telling me it would be 3hrs. Reboot the router and the video plays fine, also the same Win7 machine is reporting only 19 minutes to copy the file. The router had 20 days uptime prior to reboot. This is not the first time I've noticed this behavior.
Any idea what is going on? I noticed a similar slowdowns on previous Toastman builds, but don't recall anything similar on teddy_b's build 54. The only USB-related change I recall making in the past 6 months is removing my USB printer and therefore disabling USB printer support and USB 1.1. All the other settings are the same as I've been using for 18+ months. Could this be a USB 1.1 thing? The other thing I've noticed recently is the warning that maximal mount count has been reached and to run e2fsck: http://tomatousb.org/forum/t-458315/user-warn-kernel:ext3-fs-warning:maximal-mount-count-reached#post-1407677
Any thoughts as to why the USB performance is degrading over time? I've re-enabled USB 1.1 to see if that was the problem. Thanks for your help!
