OP said ipad on Evo = 1.2 Mbps

Yeah, not sure why that would be the case. Maybe some speed is lost in the translation from 3g/4g -> wifi. Only thing I can think of that's analogous is how the theoretical max speed of 802.11g is 54mbps, but you never come close to that when doing a PC-to-PC file transfer via the wifi intranet.

Novex - you are correct - 1.2 down on ipad tethering 4G with my evo.

I am going to try tethering my laptop over 4G next to eliminate the possibility the issue is related to the Ipad.

So...

ipad on work wifi = 12-13 Mbps
Evo on work wifi = 9 Mbps
ipad on Evo = 4-6 Mbps

So you are not understanding why the iPad isn't getting higher speeds when tethered to the Evo? And the Evo is on the 4G network as you mentioned...

Here's the deal, the Evo isn't receiving data that quickly when on the cellular network. Your work wifi may be pushing 9 or 12-13 Mbps, but that doesn't have any correlation to the sprint network. I hear 4-6 Mbps is pretty darn good.

I think you misrepresented the various speeds Wiltok cited. The O.P. states that his tower to device (4G) speed is 4-6 mbps. The problem is that the Ipad's network connection through the Evo's 4G only yields 1.2 mbps. Additionally, the Evo loses roughly 30% of his workplace Wi-fi bandwidth.

I'm unfamiliar with the Ipad so I don't know what, if any, anti-virus or firewalls may be on board. I know from experience that Sprint 4G Hotspot Wi-fi tether running 2.1, and AVG don't play well together. I could be getting 8+ mbps tower to device and the laptop would crap out at 1.2 mbps. In desperation for a fix, I prepared to run Trend Micro House Call and uninstalled the AVG. I went to the T.M. site to start the download and thought the laptop was a bit snappier. I ran a speed test and shazam! Problem solved... sort of. The Evo and Hotspot will eat alot of bandwidth (40%-50%). PdaNet will eat considerably less, and Easytether will eat still less yet.

So, are you saying that using your WiFi hot spot will give you a slower download rate than wired tethering?
I've used 4g with wired tethering (pdanet) and gotten a 7.3 download speed kn my laptop. But i havent gotten to try 4g with wireless. That's interesting. I'll have to keep an eye on that and keep it in mind..

Yes.

I didn't notice any problems with Sprint's Wi-Fi tethering (Hotspot) until after the 2.2 update. Until that point, I was able to stream Netflix (in very good, but sub-HD quality) with no interuptions to the buffer. Post 2.2, Hotspot has been running about 50%-60% of tower to device speeds. To make matters worse, Clear's network speeds in Baltimore have been in the toilet for the past couple of weeks. 50% of 5 mbps is doable. 50% of 2.5 mbps is not.

I installed PdaNet and Easytether (free versions) and tested them back to back with Sprint's Hotspot. Wow!!
Hotspot 50%-60% through speeds
PdaNet 75%-90% through speeds
Easytether 110% throughspeeds.

It would seem that there is some loss to network speed just using the Evo and Flash.
To be honest, once I saw the first results from Easytether, running any more speed tests seemed like a waste of time.
Running Easytether, I'm now watching Netflix in full HD, as long as Clear can deliver 5+ mbps network speed. I canceled Hotspot today.

Wasn't there a change to support "N" networks in Froyo? Take a look at the link below - unless I am confusing things.

[HOW-TO] Enabling Wireless N on Evo- Android Eclair 2.1 - xda-developers

I wonder if that has something to do with your issue? I am still on 2.1 so I thought maybe that is why my Ipad tethering speeds were low. But it doesn't make sense since my work wifi connection is so fast. Again, not a wifi expert so I may not know what I am talking about.
