I have a DNS323 connected through a DGS2208 switch, Cat 5e cables.  Ran through tests with different jumbo frames settings and got the following results - all in megabytes per second (MBps).

Jumbo MTU	Read MBps	Write MBps
Disabled	20	16
3000	26	17
4000	28	18
5000	32	18
6000	32	18
7000	33	17

Those are all the MTU settings my mobo supports.  Stuck with 6000 MTU based on the results.

I thought about making some Cat 6 cables and trying it out - I've read it's theoretically faster - but don't know if it's worth the effort.  Does anyone have an opinion?

CAT5e cable meets spec for gigabit (as in fact, does CAT5) - assuming your installation meets specification, you will see no change in performance by switching to CAT6.

The physical difference between CAT5, CAT5e & CAT6 is the number of twists per inch - the "tighter" the twist, the better the noise rejection of the cable - so CAT6 is no "faster" - it's less noisy.
