[Koha] Koha Performance Issue

Out of curiosity, does the amount of RAM make a significant difference?
I've been trying to troubleshoot performance issues because of both network
lag at our location. In trying to optimize the page-load speed during
checkout, I've also upped the serve RAM to from 1gig to 4gigs. While that
obviously doesn't address actual network lag (eg. bad pings or lost
packets) it can at least help me verify if the issue is with my Koha server
or with the building network. We are in a leased building, and have no
control over the network infrastructure, so if I can rule out the server as
a speed hindrance, then I can restart the conversation with IT.
