4.1.4 Estimating the size of memory used by an EADS server

The following shows the formula for estimating the size of memory used by an EADS server.

Size of memory used by an EADS server (megabytes) =

Java heap size + explicit heap size + 150

+ (maximum number of simultaneous connections to the EADS server [Figure] data multiplicity) [Figure] 52 [Figure] 1,024

Maximum number of simultaneous connections to the EADS server:

eads.server.maxConnections parameter value in the server properties

Data multiplicity:

eads.replication.factor parameter value in the shared properties
