Smaller updates, but not necessary faster

"Faster" depends on your RAM/CPU/Network.

On a very slow line with a fast CPU and a lot of RAM it might be faster. On an old computer with a fat line it will be slower because regenerating the RPM from the delta-RPM is an intensive task.

Everybody with more than 2mbit should disable the presto-plugin for yum IMO.

kragil: you're basically right, but rather exaggerating. We use xz at a low compression level for the deltas, and the CPU intensity isn't as high as you imply. It's actually faster than downloading even on my very weedy Vaio P.

Well, on every machine I ran Fedora (which I don't anymore) the heavy usage of the disk when applying updates really got on my nerves.

TBH I think Suses Delta-RPM (which Fedora now after a few years adopted) is a second-rate solution. Googles Courier patches are much nicer. I hope .deb based distros will skip this regenerating of packages idea and go right to a good solution. ( .. maybe ChromeOS will .. nobody (outside Google) knows .. )

Not true. Even on a fairly high bandwidth connection, yum-presto is definitely faster for me at work.

Then you probably have fast machines. On Netbooks or old computers presto sucks big fat donkey dong and I am _not_ exaggerating. Downloading with a fast line is basically effortless. Regenerating the RPMs isn't and it basically just froze my netbook (EeePC 901)

I would rather wait a few minutes for updates being applied than have to download over 100MB of patches for something like Open office.

It would also be cool if this type of update works for upgrading between major versions of the distributions. For example if you have installed all the current updates for Fedora 11 you could delta upgrade to Fedora 12 (And non delta packages used when delta is not possible).

It all really depends on the speed of your machine, but as far as I'm concerned presto had been a big help. I no longer cringe at 300-400Mb of updates.
