In all experiments, the server was a Digital Personal Workstation 500au (500Mhz 21164, 8KB I-cache, 8KB D-cache, 96KB level 2 unified cache, 2MB level 3 unified cache, SPECint95 = 12.3, 128MB of RAM), running our modified version of Digital UNIX 4.0D. The client machines were 166MHz Pentium Pro PCs, with 64MB of memory, and running FreeBSD 2.2.5. All experiments ran over a private 100Mbps switched Fast Ethernet.
Our server software was a single-process event-driven program derived from thttpd [44]. We started from a modified version of thttpd with numerous performance improvements, and changed it to optionally use resource containers. Our clients used the S-Client software [4].
