MBP Sluggish - Maverick or something else?

I've followed the various 'mac running slow' discussions and would appreciate assistance since I am encountering the same issues. Loading anything (apps, web pages, finder screens, etc) takes so much longer, I would say, since installing Maverick OS, but don't want to assume that since it may be something else that is loaded but stealth. Mine is MBP mid 2010, 2.53 ghz intel core i5, OSX 10.9.5, use TmMach to b/up. Have not run etrecheck yet. Any help is appreciated. Thanks.
