I'm a little leery of performance claims based on benchmark testing. But I must admit that my experiences with the 8.10 Ibex release have left me disappointed with overall performance, and frustrated over several hardware issues.
The general feeling I got from 8.10 was a certain sluggishness not felt in 8.04.
Kubuntu seemed marginally better with regards to speed, but it also introduced a lot of hardware issues that were real show-stoppers for me. I think a lot of it has to do with the NVIDIA chipset on my mobo, but many of these hardware problems weren't there when I was running the standard Ubuntu version. Jockey and KMix in particular were very problematic. Both apps would often crash without regard to whatever else I was doing.
A couple of other issues:
The Kubu Aptitude package manager seems to be a lot more cumbersome than it used to be.
DVD playback of movies is very touch and go. Totem is virtually useless since it sometimes works and sometimes doesn't. MPlayer is not much better. Also - if the DVD language selection is set to automatic, Ubuntu now defaults to Spanish even though it implies that English is the default. The only way I could get consistent playback and listenable sound levels was if I used VLC for my media player.
Sound - don't get me started on the whole PulseAudio debate. (IMHO Pulse sucks.) Suffice to say sound is a major problem for me with the Ibex (Gnome and KDE) release. Once I'm fully booted to the desktop, my speakers start emitting an obnoxious low hum (around 80hz) that sounds like a ground loop. No amount of tinkering with various system settings fixes this annoyance. This problem doesn't occur when booting up under 8.04.Overall impression - sluggish and buggy. nope..nope..nope..nope..
Not even close. I think you'd be better off giving this release a month or so for the updates to catch up with the problems.
I'll be keeping 8.04 as my production environment until things get better sorted out. As things stand, I'm thinking I'll just skip Intrepid Ibex completely
, and wait for the next (Juvenile Jackass?
That's the same strategy I'm using with WinXP and Vista!
** Note: Sorry. But I'm one of those people who think the whole Ubuntu naming schema is asinine. It was cute way back when it was Dapper Drake. It's gotten less and less amusing to me with each subsequent release.
