here you can see my server stats, normal rss should be around 100-200mb at a fully cached state
the reason why its so high is because each page is cached for an hour for maximum speed (nearly every page here is 1-2ms to load, even the dynamic ones)
Memory usage:
rss: 116MB, heapTotal: 37MB, heapUsed: 34MB, external: 2MB
Uptime:
19 days, 16 hours, 54 minutes, and 36 seconds
