Enabling Jumbo Frames breaks Frontview

What version of RAIDiator are you running?

Have you enabled Jumbo Frames on your PC's NIC and on your router/switch? Have you verified that your router/switch and PC's NIC support Jumbo Frames? Are your PC's NIC drivers up to date?

Are you using Cat5e or newer ethernet cables?

Also some routers/switches and PC NICs may support Jumbo Frames but not the full 9000 MTU. You could try setting a smaller MTU than 9000.

Is you client PC/Mac connected via ethernet or wireless to your network? If by wireless do you still get the issue if connected via ethernet?

Also, if you aren't running a gigabit ethernet network you can't use jumbo frames.

ReadyNAS is pretty good at detecting when jumbo frames don't work (and falling back to a normal MTU). However jumbo frames are not in the ethernet standard, and the one reason is that there are cases where that kind of detection fails.

Even when jumbo frames do work, they don't always improve performance - and some users here have found that they hurt performance. The main benefit of jumbo frames is reduction of CPU load (by reducing packets per second). Modern NIC cards have other features which can accomplish that for normal frames (interrupt moderation and offload processing for instance). And if your CPU is fast enough, the reduction isn't needed.

You can possibly try a direct connect to your PC instead of the OS reload. If the issue is in your network (and not the PC) then that should work. It would also help you figure out what the performance boost might be.

If you are seeing other issues (when jumbo frames are turned off) you might want to take advantage of your 90 day phone support. Or post those issues here in separate threads.
