There are many factors that can cause such inconsistent performance.

"Kids obviously are going in there with a skill that causes better performance," he said.

The numbers do not prove that corruption directly causes poor performance.

Overheating can be a serious problem with computers, causing performance to suffer to the point of a system failure in some cases.

As we've seen earlier, pipeline stalls cause the processor's completion rate and performance to drop.

Use of improper or contaminated fuel could cause poor performance, a fire or an explosion.

This inadequacy will cause poor performance and subsequently result in the fulfillment of the initial projection.

This method is simple causing poor performance because every process is treated equally.

Brownouts can cause poor performance of equipment or even incorrect operation.

The researchers said their findings did not necessarily mean that greater board independence caused poor performance.
