My question is if our webserver would benefit from having a faster network connection, even if the current 100Mb/s connection is not maxed out.
Our webserver is serving around 1.000.000 dynamic pages/day which translates to 20GB of daily traffic. Its internet uplink, which is 100Mb/s, has an average utilization of 10%. CPU usage can, at times, be quite high, so we are planning to upgrade soon, probably using 2 webservers and a load balancer in the future.
I currently believe that a Gbit uplink would be a major benefit too. Our favoured hosting provider (who can't offer 1Gbit uplink) instead tells me that it would not be a real benefit. He tells us that the load balancing makes a faster uplink unnecessary.
I am not really confident of this but can't really find much useful advice on this. We really want so serve our pages as fast as possible, so what would you recommend (in general)?
