One of the old Goa'uld hyperdrives could have ships going at 32000 times the speed of light. So if my calculation isn't wrong (though its entirely possible it is, I suck at math), an old Goa'uld ship could travel 1 lightyear in around 16 minutes. And that's like the slowest ship in the stargate universe, from that point on, they only get faster.

Indeed these are completely different universes, different circumstances, differences are to be expected. Still, in order for the RP to be... well... not shite, all speeds from the different universes will be roughly equalized. If it weren't, well it would have taken the Creed quite a bit longer to reach earth.

Or... OR... It could be interesting seeing the player ships try to make in-universe drives work with their ships. Like trying to salvage them from the Goa'uld. That could make things interesting too.
Though your really quick warp to earth would still have to be explained somehow...
