Abstract
Delay commands are injected into sequential input/output (I/O) requests and the effects of the injected delay commands are measured for determining whether a storage system handling the sequential input/output (IO) requests is causing a bottleneck, while the processing of sequential I/O requests is delayed for a time period when injecting the delay command.
