Title
A light-weight, temporary file system for large-scale Web servers
Abstract
Several recent studies have pointed out that file I/Os can be a major performance bottleneck for some large Web servers. Large I/O buffer caches often do not work effectively for large servers. This paper presents a novel, lightweight, temporary file system called TFS that can effectively improve I/O performance for large servers. TFS is a more cost-effective scheme compared to the full caching policy for large servers. It is a user-level application that manages files on a raw disk or raw disk partition and works in conjunction with a file system as an I/O accelerator. Since the entire system works in the user space, it is easy and inexpensive to implement and maintain. It also has good portability. TFS uses a novel disk storage subsystem called cluster-structured storage system (CSS) to manage files. CSS uses only large disk reads and writes and does no have garbage collection problems. Comprehensive trace-driven simulation experiments show that, TFS achieves up to 160% better system throughput and reduces up to 77% I/O latency per URL operation than that in a traditional Unix fast file system in large Web servers.
