Blackberry ENTERPRISE SERVER FOR IBM LOTUS DOMINO - - PERFORMANCE BENCHMARKING GUIDE Manual page 31

6: IBM Lotus Domino performance test results
If you have a high disk queue length or a high number of disk transfers /sec, the observed increase in disk traffic
might impact your environment. Before BlackBerry user accounts were enabled, the average disk queue length
and disk transfers /sec were well below the accepted maximum level for this environment during the baseline.
The impact observed by RIM is specific to the workload applied and might vary from site to site. The relative
impact observed occurs only on messaging traffic specific to what the BlackBerry Enterprise Server redirects. The
impact is not a multiplier that can be applied to existing disk traffic because the impact might also include disk
activity from other applications, backups occurring on the disk subsystem, or other IBM Lotus Domino traffic not
specific to BlackBerry redirection.
