Firewall Performance Subtest
(avalanche manual: Test methodologies)

Subtests
The firewall test provides five performance subtests that help you determine the firewall's operational range:

Maximum TCP Connection Establishment Rate determines how many new connections per second you can establish through the firewall. It is a performance test to evaluate the firewall's processing speed.
Concurrent TCP Connection Capacity is a performance assessment of memory size. It determines the maximum number of TCP connections that you can establish and sustain through the firewall. The connection state is maintained in a large table in the firewall's memory.
TCP Connection Rate Examination determines how many connections per second can be added to those already established through the firewall. This test is an extension of the Maximum TCP Connection Rate and Concurrent TCP Connection Capacity tests. It stresses both processing speed and memory of the firewall.
Maximum HTTP Transaction Rate (bytes) determines how many HTTP GETs per second you can sustain through the firewall.
HTTP Transfer Rate determines the rate (Kbps) at which HTTP objects pass through the firewall.

====================================================================================
Maximum connections/second. The number of simultaneous network connections initiated from Avalanche per second. (Opens and then closes the connection after the GET.)
Maximum open connections. The upper limit for the number of open connections created throughout the test. (Opens a connection and then leaves the connection open.)
Maximum transactions/second. The number of simultaneous transactions generated per second. Each transaction is the request and transfer of one object, which for a Web site is called a hit.
