CPU is the main resource for any hosting.
How can your page load slow when using Google Analytics?
Analytics code is added at the end of page. Moreover all these code are loaded asynchronously. So I am not sure how is it slowing page?
You could try getclicky, haveamint and piwik.
You can try
clickmeter

Bevo media is similar as google analytics.
Rather than just listing options – how about telling us a bit more about them? Things like … what do they do well, why are they better than Google Analytics, if you’ve had any problems using them.
That would absolutely be Piwik, which you install and host for yourself.
Good thing - you have control and you own all your data. analytics is probably more accurate and has rich features and good real-time data.
Bad thing - server capability (ram usage + huge databases after some time) in case of having a high traffic site. Some people have a separate dedicated hosting just to run Piwik.
