If your goal includes living a long perceived life, then slowing down would be counterproductive. Besides, you can simulate a lot during that kind of time period if you have a portable energy source.
So Giovanni, I see a reason to speed up, but slightly less reason to slow down.
In about 1.2 trillion years the background radiation will reach 10^-30 K and then stay there due to horizon radiation.
Since the cost of computation scales as kTln(2), that means that the same energy endowment can give you 10^30 times more computation if you save it till then than if you used it now.
If you only care about the absolute amount of computation you can do (for example a 'solipsist' virtual civilization wanting to max its own subjective time of survival and internal richness), then it makes sense to pause until the late era.
