Abstract

This paper discusses the performance implications of using server-based locking instead of shared memory locking in an input/output (IO) intensive benchmark. Uniprocessor and multiprocessor systems were investigated. Server-based locking was not a problem in uniprocessor runs or in multiprocessor runs that were processor limited. Server-based locking resulted in a significant degradation in throughput of IO limited multiprocessor runs.
