Reducing Memory Consumption - Additional Tutorials - Getting started

By default the main Exply process consumes 1 GB of memory. This is usually a fair trade–off between performance and resource footprint.

If you want to change it you might experience poor performance or out of memory errors. However you can give it a try by editing the exply-server.conf and the exply-server.service. You will find commented placeholders to adjust the memory consumption.

We recommend the minimal and maximal head size to be equal and not more than 50 % of the available memory. NewSize should be 1/3 of the heap size. Be sure to keep the settings in the two files in sync.

exply-server.conf

This file resides in /etc/init with the follow default content.

Depending on your operating system you can adjust the memory allocation in a similar way:

Just make sure Exply starts with the correct JAVA_OPTS.
