I cant imagine hitting 8000 datablocks, or downloading all the files from a server with that many datablocks. How many and what add-ons do you have? I'm really curious what you're doing to warrant the need for an increased limit. Sounds really big, kindof exciting actually.
I have downloaded a whoppin' whole entire RTB archive from a website that goes by the name of swololo (yes, that is really the website name.) It's about 0.9 GB (999.06 MB). And if you have that whole RTB archive downloaded, it should be faster upon loading next time.
The thing is just I don't understand
why there is an datablock limit, and I know you don't want to be sitting hours for 9000+ addons to download, but hey, if you downloaded that whole RTB archive, then it should be faster then!
(only if you have good internet)
