Slow Safari....Mavericks Update???

Do you have any anti-virus software installed? Such software has been known to cause browser issues. What about other browser extensions? In Safari's preferences window, click the Extensions icon... What shows up there?

As for the issues not related to the browser, see my Mac Performance Guide:

http://www.thesafemac.com/mpg

I have exactly the same issues on my iMac and do not have anti-virus software installed. I received one reply suggesting I re-index Spotlight, but this has not made any difference.

Third party cleaning utilities are not necessary on a Mac and can do more harm than good.

Your Mac runs maintenance in the background for you > Mac OS X: About background maintenance tasks

Apps such as LIttle Snitch, MacKeeper, and Growl can cause the issues you are describing for Safari.

Try this for Safari on one Mac ...

Open a Finder window. From the Finder menu bar click Go > Go to Folder

Type or copy paste the following:

~/Library/Caches/com.apple.Safari/Cache.db

Click Go then move the Cache.db file to the Trash.

Quit and relaunch Safari to test.

If that didn't help, try troubleshooting extensions and third party plug-ins.

From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test. If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.

If it's not an extensions issue, try troubleshooting third party plug-ins.

Back to Safari > Preferences. This time select the Security tab. Deselect: Allow all other plug-ins. Quit and relaunch Safari to test.

If that made a difference, instructions for troubleshooting plugins here.

no anti virus, and the only extension i have is 1password

1Password isn't a problem, I have that one installed myself.

thanks, and further help/ideas would be great.

Well, further help is in the Mac Performance Guide I gave you a link to. Have you looked there yet?

Many thanks Thomas and especially for writing in simple terms for those of us not up to programming level!. Clearing the caches has definitely improved performance, although it is not back to the level I had before moving to Mavericks. I will look for your Mac Performance Guide to see if there is anything else I can improve.

Slainte to all!

Just read Thomas' Mac Performance Guide ~ what a great, clear piece of instruction. Thanks again.

Trying running this program and then copy and paste the output in a reply. Please use copy and paste as screen shots can be hard to read.

Etrecheck – System Information

I have had the same experience, improved after clearing caches, but now very slow again. Eric, if I paste output from Etrecheck, would you be kind enough to review it for me. Many thanks, Will

I experience slow Safari and even slower Finder on Mavericks. I did some clear the Safari caches dance at some point, the performance improved but degraded again after a week or two. I stopped using Safari and use Firefox instead and the performance issues are gone now.
