2.0.0.12 firmware has some performance problems compare to the latest firmware (3.2.0.7). I highly recommend updating to the latest firmware. Be sure and follow the upgrade instructions CARFULLY. Specifically, update each switch separately, with no network traffic and update the bootcode from the bootcode, not the application firm.
Is the vlan 102 traffic traveling across the stacking links? Do you get the same performance when using a single switch? what are the other switches in your network?
First thing to note is that 10.1.1.100 is on the same subnet as the NAS and for that reason there is no VLAN routing taking place. This will a count for some of the loss. Have you done a sniff on the this issue to see if you are getting fragmentation?
I'm confused with your statement. No problems are encountered when going from 10.1.1.x to the NAS, only hosts from 10.2.2.x that go to the NAS. See the included link to an image for more information on how our setup is.
Given the 2 switches are stacked (with stacking cable), I presume they are acting as 1 switch thus I would need to upgrade them together (unless you think I should unstack and upgrade). The documentation is not 100% clear about this. I intend to open a case with Dell prior to the upgrade. My 1st pass at the upgrade docs says 1st run the firmware upgrade, then run the bootcode upgrade from the boot prompt after the firmware upgrade is complete. Never done it like that before.
I have LAG's built across the switches in the stack for redundancy (say a 2 port LAG is on switch1/15 and switch 2/15). This allows for a full switch failure. The field switches are a mix of 3com 3870's and Dell PC5224's. I haven't tested with one switch for performance.
Definitely UNSTACK the switches and upgrade them separately. Updating the bootcode from the bootcode is key to avoid a chance at corrupting the flash file system of the switch.
3.2 firmware has fast master failover, so since you are counting on the multiple switches in the stack for redundancy, this will be a key feature for you.

Could you clarify something please? 10.10.1.100 is it on a different switch then the NAS? If yes, do both switches plug into your core switch?

I assume you mean 10.1.1.100.
The NAS plugs into a field switch which uplinks via LAG to the core switch. All field switches LAG up to the core switches.

Got it. When you say "update the bootcode from the bootcode", what do you mean? Does this differ from the upgrade documents?

No. Just follow the upgrade document carefully.

After performing the upgrade we observed about a 3X performance increase with inter Vlan routing.
