SAN JOSE, CA. - Jan. 22, 2008 -- A10 Networks® today announced the results of two independent performance tests conducted by The Tolly Group, which evaluate A10's AX Series Advanced Traffic Managers using the same methodology as F5's publicly available 2007 performance report. In the first test, The Tolly Group evaluated the AX 3200's performance and in the second test evaluated the AX 2100 versus F5's BIG-IP 3400. The AX Series is a new generation server load balancer that won Best of Interop Las Vegas and Best of Interop Tokyo 2007, beating the competition based on its Advanced Core Operating System (ACOS) with multi-core CPU architecture. With models for all size enterprises and service providers, the AX Series allows applications to perform as desired, especially during peak usage conditions and while leveraging multiple advanced features.
