Unfortunately it was pretty typical performance for IPS LCDs of that era to be pretty slow. At the time, IPS was just starting to become affordable, and offered much better color accuracy and viewing angle compared to TN, but they suffered from slower response times and mediocre black/contrast level performance (they even had the nickname "IPS Glow" for it). Overclocking and pixel overdriving was sometimes an option (not for 16:10 30" panels, I checked), but that would introduce overshoot ghosting which would potentially cause even worse blur.
The only reason to use 30" 16:10 monitors is for the vertical fit. Just about any modern LCD will blow them out of the water in any other performance metric.
In terms of 30" models other than the U3011, my guess is that performance will be similar, but I never used or tested them before so I can't say for sure.
