Effects of system tuning and RAM disk onthe performance of a clinical laboratoryinformation system

[摘要] Improvements in the performance of a laboratory computer systemdo not necessarily require the replacement of major portions of thesystem and may not require the acquisition of any hardware at all.Major bottlenecks may exist in the ways that the operating systemmanages its resources and the algorithm used for timesharingdecisions. Moreover, significant throughput improvements may beattainable by switching to a faster storage device if substantial diskactivity is performed. In this study the fractions of time used foreach of the types of tasks a laboratory computer system performs(e.g. applications programs, disk transfer, queue cycler) aredefined and measured. Methods for reducing the time fractions ofthe various types of overhead are evaluated by doing before and afterstudies. The combined results of the three studies indicated that a50% improvement could be gained through system tuning andfaster storage without replacement of the computer itself
