Please review the following performance considerations.
NFS Mounted File Systems
Network File Systems (NFS) are mounted file systems that are used on most UNIX/Linux systems today. However, due to the performance issues concerning NFS mounts, we recommend that all files used in the production process of Precisely products be located on the target machine's local file system. Although some Precisely products may run efficiently on NFS mounted files systems, performance and record locking issues can cause processing bottlenecks that cannot be tuned or modified for performance gains. If you choose to use NFS mounted file systems for your production processes, Precisely cannot assist in product efficiency or performance metrics.
Sorted Raw Input File
If possible, all raw data input files into Precisely products, especially files with address information, should be pre-sorted on specific fields that your process uses for matching, merging, and duplicate record elimination. Unsorted raw data input files require more processing time due to normal sequential file batch processing and caching techniques. Sorted raw data files benefit from these caching techniques. If you need more information on sorting, please contact Precisely Technical Support for assistance.
Temporary Directories (/tmp)
Precisely products use temporary directories for internal sorts and for record caching techniques. As noted above in the NFS section, if your temporary directory (typically /tmp) is located on an NFS mount for space reasons, please be aware of poor performance consequences. We recommend that your temp space be allocated on the local file system.
