That's very frequent. I think it's not necessary, and it'll produce a
high load on the master due to the disk scans. For short update
periods the amount of changes/download is small and the disk scans are
the biggest load. For now it won't be a problem because the repository
is still small but later it'll be a bottleneck. Note that it also
causes a load on the mirrors because there's a disk scan there too. I
That said, we have no problem with whatever frequency you choose.
