According to @giacomo in here a NS7 Gateway for a small enterprise (less than 100 user) can work with 2GB of RAM. Mine has 4GB, so I started to find out which serviced are consuming RAM, I found that this 3 programs are consuming quite an amount of RAM.
clamd | RSIZE = 657.9M | MEM = 26% Suricata-Main | RSIZE = 372.8M | MEM = 15% ntopng | RSIZE = 217.1M | MEM = 9%
I’m aware that clamd can demand approximately 500MB, however I’ve read that suricata can be set it to demand CPU instead of RAM, I’m still trying to figure it out how can I acomplish it since my average load is 0.44. Also ntopng according to this guide by using this two parameters -x/-X to avoid wasting memory.
