So are you..running Leopard on that emac in your sig? Last time I tried to run leopard on my ibook 1.07 ghz I about stabbed my eyes out, it was so ubelievably awful. But Tiger gets older and older by the day, and Omniweb and Camino are starting to feel sluggish and Tenfourfox borders on the unusable. Maybe I need to strip out all the intel code of 10.5.8 and see if that helps.
Mactubes is working purrr-fect-ly for me still, so maybe the update hasn't hit the USA yet.
Yep, maybe it's the GB of ram but Leopard has always run smoothly on my eMac. I never had the opportunity to test Tiger on this machine. Back in 2008 i went directly from Panther to Leopard. I remember that at the time I found 10.5 faster than 10.3, but that could have been just an impression, or maybe my system really needed a reinstall. With sufficient ram, I think that the extra software is worth the Leopard upgrade. If you have enough HD space the best solution may be installing Tiger and Leopard on different partitions. I'm tempted to do this myself (with Panther instead of Tiger) so that I can play with Classic again. I'm itching to try Classilla, plus I wonder how 10.3 would feel in 2012.
As for Omniweb and Camino, unfortunately I think we are going to loose them soon. The Omnigroup has already announced they won't support ppc anymore. I fear Camino developers might be forced to do the same considering their forced move to Webkit. Even an hypothetical Leopard-Webkit powered Camino would only work on 10.5
TenFourFox sluggishness might be due to extensions. I've adopted a minimalistic approach with add-ons and I must say that TFF flies on my system. Unistalling Adblock plus alone has dramatically improved speed (Im using Glimmer Blocker to get rid of ads, if I was on Tiger I would probably go old school and edit the host file). VideoDownload Helper is installed but disabled. It is powerful but it works in the background and I think it tends to eat resources. At the moment I'm using only NoScript to block garbage (especially social widgets) and Unplug for video (excellent interface, only acts on request). In the rare occasions Unplug doesn't fetch video URLs I momentarily enable VideoDownload Helper. I even got rid of Flashblock, it is not needed with the right Noscript settings.
Oh, and just to return on topic, Mactubes is working fine for me as well. Maybe it's an ISP problem?
