I have a high-traffic site that is on a shared server. I have seen some packet loss in the past few months, and even some spikes in the "time spent downloading a page" graph in GWT. I am concerned that slow-loading could adversely affect both the user's experience (if they are on a slower connection) and my Google rankings (since they factor in page load time). My question is whether or not I would benefit from using a dedicated server. Will there be a noticeable difference in performance speed? Right now, according to some of the tools available online for testing webpage load time, my homepage takes 15.57 seconds on 56k, 6.57 seconds on 128K, 2.94s on T1.
Those seem like very small numbers, but the spikes in load time as shown in Google Webmaster Tools concern me. Would I benefit from a dedicated server?
Apologies if this is in the wrong forum, but I am on an Apache Server.
