More Safari Slowness

Question

[ Edited by Apple Discussions Moderator; Please start a new topic about your technical issue. ]
There is a real problem with Safari that is not just isolated to something on one machine. I have seen this issue on several Macs. It seems to have been doing this since 10.4.4, or possibly 10.4.5.
When I open a certain number of tabs, or Windows, Safari will suddenly grind to a halt. Looking at processor usage via command-line top command shows me that Safari is using upwards of 85% of processor time. The spinning beach ball and sluggish performance concur with this. Doing such things as changing tabs, changing windows, or even scrolling sends that beach ball into spinning mode.
I have done the usual things... emptied caches, dumped icons, repaired permissions, etc. This is DEFINITELY a problem that was just introduced in one of the last two updates, because it did not do this before. Furthermore, it is doing this on more than one machine.
This combination of websites opened in as a tabset is sufficient to get Safari into this crawling mode.

Skip, et al . . .
Do you have ANY third party "Internet Enhancing" apps on there? Programs like SpeedDownload, iGetter, PithHelmet, Acid Search, Safari Enhancer may need updating. Also Norton apps and Virex can cause havoc.
Also, here's a good list of basics:
1. Empty your cache & History settings via the Safari menu
2. Trash your Icons Folder:
HD>Users>Home>YourName>Library>Safari -->Icons
Restart Safari and a new folder will be automatically regenerated.
(This folder saves favicons of all the sites you visit. Needs cleaning periodically -- or you can change that file's preferences to "Read Only"
rather than "Read & Write." This will keep it from growing in size.)
3. You might want to check all three "auto" preferences in Safari. Sometimes those lists gets very long and need pruning. (I turned all autofill boxes off, and have no problems.)
4. Launch Font Book and check all fonts for duplicates. A duplicated font will have a bullet beside the font family and you can resolve duplicates by selecting the font and at the menu bar, go to Edit > Resolve Duplicates.
Do this for each font with a bullet next to it.
If you're still having problems:
5. Shut down your computer . . . unplug the computer, modem, and router, if you have one. Let everything sit for 2-3 minutes. Plug everything back in, start up your modem & router, then restart your computer.
Hope this helps
