each Cisco ACE module was brought online.  In 
addition to the linear scalability tests across four 
Cisco ACE modules, the second scalability test 
demonstrated how the Cisco ACE enables 
scaling from 4 Gbps to 8 Gbps to 16 Gbps of 
throughput on a single Cisco ACE module using 
only a software license upgrade.  
 
 
Performance Results
 
 
L4 CPS:  
The Layer 4 connections per second (CPS), 
concurrent connections, and throughput tests for 
various server response file sizes were 
performed on the Cisco ACE.  Across the file 
sizes tested, the Cisco ACE demonstrated 
consistently strong performance.  At the largest 
server response file size (64K bytes), Spirent 
Avalanche reached its CPS (~4.5K per device) 
generation limit inhibiting the ability to determine 
the maximum CPS limit for large server 
response file size on the Cisco ACE module.

superior ability to create and process connections across a range 
of transmitted file sizes. 
 
L4 Concurrent:  
The Layer 4 Concurrent test results showed that 
the Cisco ACE handled almost 4 million 
bidirectional connections (Chart 4).  Each of 
these connections represents both the client-to-
DUT as well as the DUT-to-server side of the 
connection.

L4 Throughput:  
The Layer 4 throughput test at different response 
file sizes shows a consistently strong 
performance by the Cisco ACE.  From files sizes 
of 512K down to 2K (Chart 1, cover), the Cisco 
ACE maintained a performance of greater than 
12 Gbps. 
 
L7 Results:  
These Layer 7 tests differ from the Layer 4 
series, as the traffic generated requires the 
device under test (DUT) to perform TCP 
termination, analyzing at least the first data 
packet after the TCP setup sequence (SYN / 
SYN_ACK / ACK) in order to make an intelligent 
switching decision.
