Improving Node.js performance

You can take various actions to improve the performance of Node.js applications.

Modifying the enclave of a NODEJSAPP with DFHSJNRO
DFHSJNRO is a sample program that provides a default set of runtime options for the Language Environment® enclave in which a Node.js application runs. For example, it defines storage allocation parameters for the Node.js process. It is not possible to provide default runtime options that are optimized for all workloads.
Calculating storage requirements for Node.js applications
To start one or more Node.js applications in a CICS region, you must ensure that there is enough free storage available for each Node.js application to use. CICS and other products that are running in the same region might require a considerable amount of z/OS® storage. CICS storage allocation parameters such as DSALIM and EDSALIM affect storage availability and might be over-allocated compared to the peak requirements.
