The classic and no harm solution to mysterious browser slowdowns is to clear the cache.
You don't need any third party utility or hunting the file via finder. Just "Empty Cache" from "Safari" menu.
Also you may try (if not already) updating Flash plugin in case it is older than 10. Version 10 has many speed optimisations, acceleration etc.
The following usually works on both Tiger and Leopard:
(First, if yours is an Intel Mac, check that Safari is not running in Rosetta, which is enough to slow it to a crawl.)
Many, including me, have had success with adding DNS codes to their Network Settings, with good results in terms of speed-up:
Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu. Click on TCP/IP and in the box marked 'DNS Servers' enter the following two numbers:
Click on Apply Now and close the window.
Restart Safari, and repair permissions.
If that didn't do it, then try this as well:
Empty Safari's cache (from the Safari menu), then close Safari.
Go to Home/Library/Safari and delete the following files:
Then go to Home/Library/Preferences and delete
Repair permissions (in Disk Utility).
Start up Safari again, and things should have improved.
Less likely, but possible, is that the slowness is caused by a Trojan such as the one called 'DNSChanger' or 'OSZ.RSPlug', which can alter the DNS settings of your network connection. .
If you have agreed to that installation, your system can be infected and your DNS settings altered, which results in your system using the wrong DNS servers, which can slow web surfing to a crawl.
This can be fixed by downloading and running a freeware utility called DNSChanger Removal Tool which you can download from here:
Once you have run that utility you have to re-boot your Mac, then reset Safari, and re-enter your DNS settings in System Preferences/Network.
