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: 133MB, heapTotal: 14MB, heapUsed: 25MB, external: 15MB
Uptime:
1 days, 7 hours, 24 minutes, and 13 seconds
