 ## VM Sizing
 Sizing depends on the number of prefixes being monitored and the number of BGP updates

 Memory is not such as big deal in terms of data collection. It's more on the SQL queries that
 require a lot of memory.  The number of connections makes a **huge** difference.  If you

+plan to support many connections accessing and running queries, you will need more
 memory.  You should be able to support <= 100 concurrent connections to PostgreSQL
 with a system that has **32GB of RAM**. Responses times to queries that use indexes
 should be less than 2 seconds.  
 
 The number of vCPUs is also driven by the number of concurrent connections to
 PostgreSQL.  A good starting point is to have at least **16 vCPUs**.
 
+Small deployments with less than 1M prefixes and less than 100,000 updates per day can easily run on a system
+with 4vCPUs, 4GB RAM and 80GB disk (<1000 IOPS).  Please **note** that [RPKI validator](https://github.com/RIPE-NCC/rpki-validator-3) tends to take up a bit
+of memory.  It would be better if you disabled RPKI validator for a small deployment where you have <= 4GB ram.  Surprisingly
+RPKI validator requires greater than 2GB RAM. It also is pretty CPU intensive at times.  Looking to switch RPKI validator
+for a better memory and cpu focused implementation.   
 
 ## Docker Containers
 There are several docker containers defined in [docker-compose](https://github.com/OpenBMP/obmp-docker/blob/main/docker-compose.yml).
