Benchmarking Tips

The following are tips for benchmarking HSE applications.

System Requirements

The system running the HSE application should meet the specified requirements. Be certain to:

• Configure huge pages and other virtual memory tuning parameters
• Balance block storage devices across NUMA nodes, when applicable, and configure read-ahead

Configuration Parameters

In the HSE application or kvdb.conf file, provide appropriate values for at least the following parameters.

KVDB parameters:

• throttling.init_policy as determined by hse storage profile in the common case where the KVDB is configured with a capacity media class
• durability.interval_ms as appropriate for the application
• durability.mclass representing the fastest tier of storage configured for the KVDB

KVS parameters:

• mclass.policy maximizing the use of faster tiers of storage for all KVSs when multiple media classes are configured for a KVDB
• value.compression.default=on for all KVSs, unless the application performs its own value compression or values are known to not compress
