Description (partial)

Very intermittent latency of 30-60ms may be experienced in traffic that is redirected to an SFR module on the ASA 5500-X platforms.  This latency is seen on approximately .02% of traffic (or 1 in every 5,000 packets). While this is generally unnoticeable, it may impact applications that are especially sensitive to high latency.  This latency introduction is expected behavior due to platform-related constraints.

This behavior is observed when sending traffic through an SFR module for inspection on an ASA 5500-X platform
