My web host is bugging me to upgrade to a better plan because my multisite network is taking up too many resources on the server (I'm on a reseller plan and I'm the only customer). That's to be expected I know but I'm curious to what usually causes high resources usage on multisite. Is it plugins?
I average about 7k visits & 10k pageviews per month in total across all sites on my multisite install. Appreciate any insight and stories from you guys.
