Recommended Sizing for Extra Large Profiles of the On Premises EUM Server and the Events Service
This article recommends hardware specifications for an extra-large profile for the on-premises EUM Server with the Events Service and then shows you the performance for different use cases that use EUM products. You can use the information to better understand the expected performance and make adjustments accordingly.

Review the following: On-Premises EUM Server Sizing Guide to:
Hardware Specifications
You are recommended to use an:
- EUM Server: one machine with 32 vCPU and 256 GB of memory or AWS EC2 instances of type r5n.8xlarge for the EUM Server
- Events Service: refer to XL Profile sizing in the How do I size the Events Service? (i.e., Events Service T-shirt Sizing Guide)
JVM Options for the EUM Server
The following JVM Options were used in testing and are recommended for the extra-large profile.
DEFAULT_JVM_OPTS="\
\"-server\" \
\"-XX:+UseConcMarkSweepGC\" \
\"-XX:CMSInitiatingOccupancyFraction=50\" \
\"-XX:+HeapDumpOnOutOfMemoryError\" \
\"-XX:NewRatio=1\" \
\"-Xms178603m\" \"-Xmx178603m\" \
\"-javaagent:/home/ubuntu/javaagent/javaagent.jar\" \
\"-DEUM_COMPONENT=processor\" \
\"-Dlogback.configurationFile=bin/logback.xml\" \
\"-Dcom.mchange.v2.c3p0.cfg.xml=bin/c3p0.xml\""
Use Cases and Load Profiles
To help you better understand the performance expected of the extra-large profile, tests were run for different EUM products with distinct load profiles. The table below lists the EUM products used and their load profiles. For more details, see the load profiles in the following sections.
