Optimizing session manager (SSM) performance

You can optimize the IBM® Spectrum Symphony session manager (SSM) using various techniques.

Optimizing flow control for SSM
Optimize the IBM Spectrum Symphony session manager (SSM) through flow control. Flow control prevents session manager from exhausting critical system resources, which may occur under extreme workload.
Reducing Linux memory fragmentation
The Linux® malloc_trim function releases free memory from Linux heap. You can leverage malloc_trim with IBM Spectrum Symphony on Linux to enable it in SSM. This way, you can control how often free memory is released from the heap, therefore, reducing memory fragmentation for IBM Spectrum Symphony on Linux.
Optimizing history file operations
Configure history settings to optimize session manager (SSM) performance in your cluster.
Reducing the size of history files and disk usage
By default, SSM persists all history attributes, but to reduce the size of history files and to save disk usage, you can minimize this to only basic attributes. The less attributes you specify (that is, basic versus full attributes), the better the SSM performance.
