I don't know how anaconda handles it but the default raid IO limits are very conservative (optimized for background work on a live system)
On a system being created it's probably a better idea to tell the raid system to pump as much blocks as possible, since this is a blocking op in this context and we don't care about anything else.
I think you miss the point. On a file system which is being created, the bandwidth limits _ought_ to be fairly much irrelevant.
No they're not. If I remember well during an update anaconda can transform some existing logical volumes to redundant volumes, so you can have a fairly big mass of data to transfer.
And the bandwidth limits are *very* conservative. You won't win 5% or even half the time, sometimes it's a 10x (+) différence.
