Research Report

Description:
The Tolly Performance report shows you how Citrix NetScaler significantly outperforms F5. In head-to-head testing, NetScaler delivered Web traffic at least 3X faster “right out of the box” with significantly lower latency, CPU utilization and higher throughput.

Citrix Systems Research Report Sample

Testers noted that the CPUs of the F5 device were fully taxed even at the lowest level of concurrent connection, registering 90 percent utilization at only 12,000 connections. (According to F5 documentation, 10 percent of each CPU’s capacity is reserved for management functions.)

To characterize BIG-IP performance at lower CPU levels testers throttled back the load on the BIG-IP, measuring CPU utilization until the load was found that would drive the CPU to less than 70 percent. Testers then ran the Advanced L7 test again.
