Is there any correlation between organic search rankings and my server's system resources? I have a large site and wonder if increasing my server budget will increase my rankings. Site is now over 50k pages with 1000- 1200 visitors daily over 100,000 page views monthly. I have a PRO package at Pantheon 20G. (Package says it's for up to 100,000 page views per month.) The next package is a lot more money. Don't know if it would make any difference.
Increasing your server size won't magically increase your rankings. However every second/millisecond you shave off from your page load time directly affects your rankings in almost REALTIME.
How is your DNS resolution?
Do you use any managed DNS like DYN/DNSmadeeasy?
Do you use a CDN to offload your static content?
Have you switched to SSL yet?
Do they offer SPDY for SSL?
Switching to SSL will instantly get you some noticeable improvements in rankings.
Google webmaster speed pagespeed insight says 84/100 so I would think thats a non-issue.
While pagespeed score is yet another unreliable metric, we've seen some immediate boost(~12 hrs) in rankings
for this other member after optimizing the site as per Pagespeed recommendations.

This is what he got to say after optimization : 4 new keywords already shown ranking and 2 jumped into top 3 already
Optimize your site with the current server and see how much optimization you can get out of it. The only thing you'll have to concentrate about is to reduce loading time while maintaining if not increasing the visitor experience.
