question on multiple vmotion ports on a dvswitch

I have read that esxi 5 can use multiple vmotion ports on a dvswitch to speed up vmotions, i want to verify that i set this up correctly because it doesnt seem to make a huge difference...

My dvswitch has 3 active links (1,2,3)  and 1 standby (4).

I have a standard vMotion port setup for vMotion and NFS mounts:

Then i added 3 other portgroups, and made them vMotion, selecting only 1 active nic and 2 of the other active nics as standby

vMotion 1 goes to uplink 1 with 2 and 3 in standby, and so on:

Finally, each host has 5 vmkernel ports:

vmk0 = management

vmk1 = vmotion & storage

vmk2 = vmotion1

vmk3 = vmotion2

vmk4 = vmotion3

Is that the proper way to setup mutliple vmotion ports? Is it possible to have the 3 extra vmotion ports point to all 3 active links like the first vmotion port? Could the vmotion & storage port that is pointing to all 3 uplinks cause vsphere to not use the other 3?
