Safari causing system to choke up for a min?

[honeycombz]

What are all these showing up in console. My system sort of chokes up for a min once or twice a day, might be when I open up Safari for the first time since reboot? Not sure. Sort of does the following for a min.

Also around the same time I see this in system.log

Also finding stuff related to Microsoft Keychain? Can this be deleted? What does this related to?

i also have com.apple.Webkit.Networking.xpc in Firewall options set to allow connections. Should this be blocked?

Got the lag again today. This time pinpointed it in console to 1 min and this was what the system log said.

Sep 12 07:30:50 HDD com.apple.xpc.launchd[1] (com.apple.quicklook[2067]): Endpoint has been activated through legacy launch(3) APIs. Please switch to XPC or bootstrap_check_in(): com.apple.quicklook
Sep 12 07:30:55 HDD com.apple.xpc.launchd[1] (com.apple.DumpGPURestart): Service only ran for 1 seconds. Pushing respawn out by 9 seconds.

Seems like this XPC thing pops up quite a bit around when I am having problems. I noticed in firewall options com.apple.Webkit.Networking.xpc is listed as 'allow incoming connections'. I never added it there, don't really know what this is but hoping someone might be able to shed some light on how I could resolve this?
