Increase in compensation capacitor for op-amp
The whole point of the compensation cap is to make a LPF that dominates all the higher frequency Gain-Bandwidth tradeoffs such that the net gain vs f is dominated by the C added to internal current signal. The result is a controlled open loop LPF with a breakpoint of like 10 Hz and gain of like 1e6 for a GBW product of 1e7.  

Increasing the Compensation cap x3 reduces the GBW product /3 so that closed loop gain-bandwidth is also affected but step response overshoot may be improved slightly if the compensation was not critically adjusted for critical dampening.  ( ie not as dominant at unity gain as the net attenuation from all the internal stages cascaded near 1MHz)
