Incremental updates
I too am on dialup and have multiple computers. The problem isn't that I don't have the time to just let my computer sit here downloading the weekly updates, the thing is that it takes 16 minutes on average to do it on dialup (yes, I just timed it.)
After getting the update (3/25/09) I looked inside the includes.zip that I just downloaded and it has files in it that haven't been updated in months. Those files are completely wasting bandwidth for both of us. Not to mention that the files that have been updated have been increased in size by a relatively small amount. The supplemental.zip file has 14 files in it, 3 of them are less than a month old. I don't need to download those older parts, I got them when they were new. That file wastes 116kb or 29 seconds on dialup.
A more cost effective and efficient solution would be what most updaters do, incremental updates. Where you only get the parts of the files that have been changed or at the very least the whole file that changed.
Out of the 16 files in the updated includes.zip file only 6 of them are worth updating cause the rest weren't new. It's only a savings of 86kb but over the millions of people that use this product it adds up quickly. And on our dialup it's a savings of 21 seconds just for that single file. But it could be significantly smaller by only including the NEW parts of those individual files in the compressed zip files the updater gets. I hope that incremental updates will make it into a new version of spybot someday soon.
For you broadband users, none of this matters in the slightest, but unfortunately for those of us who don't live in or very near a city ISP's just don't care about us and so we have to pick and choose how long we're going to wait just to see a website or if we really have the time to download something while we can't do anything else until it's finished.
Please consider pushing ONLY the changes and not the fluff in the updates, thanks. And sorry for necromancing this thread
