Performance and Scalability Factors
Two factors affect the performance and scalability of SRM software: hierarchy tree depth and kernel memory.
Hierarchy Tree Depth
The amount of overhead caused by the SRM scheduler is minimal in most situations, and is proportional to the number of processes and the depth of the hierarchy tree. Hierarchies with trees deeper than about 7 layers impose a significant overhead and should be avoided. It is best to keep the hierarchy tree as flat as possible.
Kernel Memory
The amount of kernel memory used by the SRM software can be significant in some cases where a large number of lnodes are created. This is most likely on systems with large number of users in the password database. An SRM lnode is about 3 kilobytes. ...
