Good point MRAB... thanks for making it.
I started to wonder the same thing, but it took me a couple hours away
from working on it and a good dinner before I saw that...
Yeah, looking at it freshly now, I agree, I think I probably would be
better off running them one at a time.
The goal is to update several directories of ISO images with nightly
builds. I can use rsync and only download images that are changed, or
I can use zsync and only download diffs (I believe that's how it
works) which is faster anyway.
The only reason I was considering doing them all simultaneously, or in
batches at least, is that I have to update 10 - 12 ISOs daily... BUT,
now that I look at it from your perspective, yeah, it would probably
be faster overall to do them one at a time instead because of the
bottleneck.
Thanks! That helped a lot (and probably saved me a lot of headache
later on) :-)
Cheers
