System performance for literature retrieval was tested, revealing a linear increase in search and download times with more active users. Despite a 16x slowdown in worst-case scenarios, the CD PLUS/Ovid system

Area of Science:

  • Medical Informatics
  • Information Science

Background:

  • The CD PLUS/Ovid literature retrieval system was implemented at Erasmus University's Faculty of Medicine and Health Sciences in August 1994.
  • The system served up to 1,200 potential users.

Purpose of the Study:

  • To evaluate the impact of concurrent end-user activity on the performance of the CD PLUS/Ovid literature retrieval system.
  • To quantify the relationship between the number of active workstations and system response times.

Main Methods:

  • System performance tests were conducted using the CD PLUS/Ovid system.
  • Search times and download times were measured under varying loads of continuously active workstations.
  • Performance was analyzed in relation to the number of concurrent users.

Main Results:

  • A linear relationship was observed between the number of active workstations and search times.
  • Download times also exhibited a linear increase with the number of active workstations.
  • In a worst-case scenario with sixteen active workstations, record retrieval and download times increased by a factor of sixteen compared to idle conditions.

Conclusions:

  • The performance degradation observed in the CD PLUS/Ovid system is linear with user load.
  • While worst-case performance impacts are significant, they are considered acceptable for real-world usage scenarios.
  • The study provides insights into the scalability and performance characteristics of early networked literature retrieval systems.
