A few users have reported slow page loading and other performance issues under the newly released Safari 5.0.
Apple Discussions poster Douglas Fritz writes:
“I downloaded Safari 5 andinstalled it last evening. Why is it so slow to open common URLs? I tried clearing the cache and deleting the history. But after opening my regular sites since the clearing, the sites still load very slow. ”
There are a number potential causes and fixes for this issue, but the most likely remedies of slowness after a Safari update include:
Disable errant plug-ins and add-ons Some plug-ins and add-ons may be incompatible with the new release of Safari, causing performance issues.
In Safari, go to Safari > Preferences in the menu bar. Click the “Security” tab, then deselect “Enable plug-ins.” Restart Safari. If the slowness is gone, a plug-in may be to blame. Look in the folders ~/Library/Internet Plug-Ins and /Library/Internet Plug-Ins and remove the items to a safe location (but don’t delete them). You can then re-enable plug-ins in the “Security tab”, and add the items back one by one, restarting Safari after each, to identify the problem plug-in.
Perform the same process for any items in the following folders:
- /Library/Input Methods/
- ~/Library/Input Methods/
Clear AutoFill and favicons Go to Safari > Preferences and select AutoFill. Click the “Edit” option next to “Other Forms” and remove all of the items.
Next, navigate to ~/Library/Safari and drag the folder “Icons” to the trash, then restart Safari.
Reset Safari Although you’ll lose some potentially valuable stored data, this very simple procedure can resolve the slowness in some cases. Simply go to Safari > Reset Safari (in the Safari menu bar) and check all items.
