A Comparison of Public Proxy Software using Wisconsin Proxy Benchmark

Jin Zhang and Pei Cao
University of Wisconsin-Madison

Following Duane's list of available proxy software, we downloaded and tried to install all of the publicly available proxy software. Here is a report of our experience. We also conducted a very preliminary test of the collection of software using a small configuration of the Wisconsin Proxy Benchmark. We report our results here.

You should read Duane's brief description of the proxy software first, and then read this document. This document includes our understanding of the architecture of the proxy products and our experience with installing and testing them.

Note: the benchmark results reported here are very preliminary, and should be in no way considered as any significant indication of the proxy's performance.

The configuration of the benchmark is described here.  For each proxy, we listed blow:


    architecture:    process based, fork one process on each request
    installation:     run make
    configure:        configuration file
    see result here


    see Squid and Netcache


    commercial product


    commercial product


    architecuture:    single process, event-driven model
    installation:        simple, just "make install"
    configure:            configuration file
    see result here


    architecture:    process based proxy, fork one process on each request
    installation:     relatively simple, may need to change a little bit of Makefile before running make
    configure:        quite a lot of command line options
    limitation:       can not specify the cache size
    see result here


    commercial product; runs on WinNT only; rumors is that it will come free with WinNT 5.0;


    architecture:     process based, pre-fork processes
    installation:      relatively simple, run configure and make
    configure:         configuration file
    limitation:        can not run without caching
    see result here

Novell BorderManager

    commercial product; runs on Novell's own operating system; in other words, software/OS integrated;


    architecture:    process-based, pre-forked processes
    configure:         configuration file
    see result here


    architecture:   thread based, pre-fork threads
    installation:     simple, run java install to install
    configure:        uses web-based interface for configuration. But need to learn much about
                              the system architecture before knowing how to configure.
    limitation:       proxy returns "HTTP/1.1 200" even if the original server returns "HTTP/1.0 200"
    see result here


    commercial product; not available to us.

Open Sesame

    commercial product;


    architecture:    thread based
    installation:      relatively simple, runs configure, make install, install
    configure:         web-based configuration interface. Need some time to figure out, but not very difficult.
    limitation:        when the server replies with "Expires:" header, the proxy does not cache the document.
    see result here


    commercial product; runs only on Windows NT.


    architecture:    thread based, create a new thread on each request.
    installation:      comes with bytecode, no installation needed after unpack the package
    configure:          configuration file, need to know a little bit about system architecuture and
                                the modules of the system.
    see result here

Cisco CacheEngine

    commercial product; integrates the proxy software and the OS;

Sun NetraServer

    commercial product; not available to us;

Inktomi TrafficServer

    commercial product; comes as both a software-only product and a software/OS integrated product. We have not been able to obtain an evaluation version.

IBM Web Traffic Express

    commercial product. We got an evaluation version off the Web, but can't install it on our Solaris 2.6 machine. The installation guide on the Web apparently only covers installation on WinNT. We simply can't figure out how to install it. IBM didn't offer much help.

Intel QuickWeb

    commercial product. Performs image compression and caching. Only available through ISPs using it. Intel claims that about three ISPs are using this product.


    commercial product. Evaluation versions not available to us.


   From Duane,    
"Packetstorm Technologies sells a caching appliance called WebSpeed which runs Squid and is configured for transparent caching. "
