Performance Considerations

Performance is usually measured in response time and throughput. A good design and indexing strategy leads to the largest performance gains.

Response Time

Response time is the time it takes for a single task to complete. Several factors affect response time:
  • Reducing contention and wait times, particularly disk I/O wait times

  • Using faster components

  • Reducing the amount of time the resources are needed (increasing concurrency)

Throughput

Throughput refers to the volume of work completed in a fixed time period. Throughput is commonly measured in transactions per second (tps), but can be measured per minute, per hour, per day, and so on.

Design Considerations

To realize the largest performance gains run Sybase IQ on a correctly configured system, establish a good design,and choose the correct indexing strategy.

Other considerations, such as hardware and network analysis, can locate bottlenecks in your installation.
