Not sure if there is a page on this matter in particular, I guess this one is the closest on the argument:
Propulsion Performance Statistics
Without descending into the (low!) sci-fi tech of Orion's Arm you can have an antimatter drive theorically reaching a peak speed of 0.7c, so, calculating refuelling and repairs you can probably go from an edge of the galaxy to the other side in 200k years, I guess. If hitting a space debris don't make you vapourize mid course
Realistically you have probably to double or triple that number but I still think a civilization can engulf a whole galaxy in less than a million year.
As Rynn said these are "mere" geological times and probably one of the strongest points of the Fermi Paradox.
Hell 1 million years is normally a tight error bar in geological time
