The dramatic increase of WWW traffic on the Internet has led to the wide use of web proxy. The web proxies can be used to improve security, save network bandwidth and reduce network latency. However, as the network bandwidth increased, the general-purpose file system is rapidly becoming the performance bottleneck of web proxies. In this paper, we propose an enhanced object management, called UNIFIED, which is a user-level technique for improving the performance of web proxy. In UNIFIED method, several techniques are developed to improve the disk I/O performance. Instead of the traditional trace-driven simulation, we employ Polygraph 2.5.4 with Polymix-3 workload to evaluate our system realistically. To investigate how the proxy performance depends on the equipped disk, we offer two sets of test machines. One is equipped with one IDE disk and the other is equipped with five SCSI disks. Experimental results show that, in both tests, our method can improve the proxy performance dramatically by reducing the overhead associated with disk I/O.
