Running Simultaneous Jobs on UNIX

Running multiple Enrichment jobs simultaneously on a UNIX system reduces performance by a factor equal to the number of jobs you are running. For example, if you run two Enrichment jobs simultaneously, performance is reduced by approximately 50 percent. You can improve performance for running multiple jobs by increasing the amount of RAM on the system. Another way to improve multi-job performance is to run one Enrichment process on one fixed disk drive and the other Enrichment process on a second fixed disk drive. Performance can further be improved if you have separate controllers, one for each fixed disk drive doing I/O.
