Object and directory sizes

Since PPS holds its objects in memory, they are small. Each object is allocated 32 kilobytes. This doesn't mean that each object uses 32 kilobytes of memory at run time; it uses only the amount of memory needed to internally represent its current attributes.

The number of PPS directories and objects is limited only by available memory. The depth of PPS directories is limited by the fact that the full pathnames of objects are stored in the persistent directory as files; the size of these pathnames is limited by the maximum filename size supported by the persistent filesystem used.
