Your update manager for Sabayon seems to take quite a while to process updates, especially if you have a lot of updates.
I have a Dell Optiplex 745, which is a 64 bit system. And, I'm on Verizon FIOS. Have to look it up to find the exact speed of my connection, but they just upgraded me. I think on a rating of 1 to 5, I have at least their 3. Being FIOS, I think from other newsgroups I've read, it's about the fastest available in the U.S.
I just did the last mega update to Sabayon, so I guess I have your operating system's latest version. I like it well enough overall. But, I have this system partitioned and using two different versions of Linux. The other one is Linux Mint Debian. My wife loves Windwoes (mispelling intentional), so I left that on our laptop. But, I decided to replace the windows on this, and Sabayon won out.
However, when I compare update speeds between the two, It seems as though the Linux Mint updates process faster. I have no easy way to do a side-by-side comparison. But, If I have roughly 50 to 100 program updates for Sabayon, they seem to take over an hour to process. I don't think Linux Mint Debian, or even Ubuntu, take this long.
So, making this faster would probably be a wonderful improvement.
Now, forgive me for going off-topic, and being too lazy to go to another forum.
But, I'd suggest a change to the desktop. Right now, you have most things hidden so that it looks elegant instead of cluttered. OK. BUT, I think programs currently running should have a thumbnail either on the desktop or along the bottom of the screen, so you can click between them, instead of having to ALT-TAB to switch between them.
Anyway, thanks for having an easier and more manageable version of GENTOO. I've just got too much chaos in my life to be able to take all the time GENTOO would require. The option of Gnome was most helpful, too.
