[WH40K] On average, how long does it take from one end of the galaxy to the other end with warp drive?

I know it's quite unstable but on average.

1 Year. At its most stable, using the Imperium's most reliable drives, travelling from one side of the galaxy to the other is about a years journey. 

The Tau take longer, but that's mostly because of course corrections, there's no reason to believe their drives are inherently slower. 

The Eldar can do it in minutes.
