Abstract

NetScaler, Inc. commissioned The Tolly Group to examine the effectiveness of the NetScaler Application Delivery System, a purpose-built appliance that provides real-time compression for application data, including the ability to compress encrypted and unencrypted data for Web and client/server applications.

The objective of this evaluation was to measure application performance improvements yielded by NetScaler’s new AppCompress Extreme technology. Tolly Group engineers tested application acceleration benefits by measuring the total round trip time (in seconds) for an actual client requesting and receiving application data from both a popular public Web site and a commonly-used enterprise application. The tests were performed using a live Internet connection whose connection speed was throttled to simulate a true end-user experience.

All performance measurements were made at Tolly Group facilities in Boca Raton, Florida and all content was hosted at NetScaler’s facilities in San Jose, California. Tolly Group engineers tested AppCompress Extreme in a variety of customer scenarios using both 56 Kbps and 256 Kbps simulated connection speeds.
