The CDR_QUEUEMEM configuration parameter specifies the maximum amount of memory that is used for the send and receive queues. If your logical logs are large, the Enterprise Replication reads a large amount of data into queues in memory. You can use CDR_QUEUEMEM to limit the amount of memory devoted to the queues.
The maximum memory used for queued elements on a replication server is the total number of database servers involved in replication, multiplied by the value of CDR_QUEUEMEM.
When you increase the value of CDR_QUEUEMEM, you reduce the number of elements that must be written to disk, which can eliminate I/O overhead. Therefore, if elements are frequently stored on disk, increase the value of CDR_QUEUEMEM. Conversely, if you set the value of CDR_QUEUEMEM too high, you might adversely impact the performance of your system. High values for CDR_QUEUEMEM also increase the time necessary for recovery. Tune the value of CDR_QUEUEMEM for the amount of memory available on your computer.
