Appendix A. Performance Data
Data Transfer Time
Note: This is the time required to transfer the data between the CPU module and the rack-based
Ethernet module. EGD data transfer times do not increase linearly in relation to data size.
Please use the data values in the table below to estimate data transfer times.
Note: CPE modules do not need to use this table with respect their embedded Ethernet port, as
there is no transfer of data across the backplane related to EGD traffic.

EGD performance is different on the IC695NIU001+ (versions-AAAA and later) compared to the IC695NIU001. In general,
consumed data exchanges with a size greater than 31 bytes will result in contributing less of a sweep time impact and data
exchanges with a size less than that will contribute slightly greater sweep impact. All produced exchanges on the
IC695NIU001+ will appear to have a slightly greater sweep impact when compared to the IC695NIU001.
