1. A method for self-detecting storage bottleneck by a processor device in a computing environment, the method comprising:

  • injecting delay commands into sequential input/output (I/O) requests and measuring effects of the injected delay commands for determining whether a storage system handling the sequential input/output (IO) requests is causing a bottleneck; and

    delaying a processing of the sequential I/O requests for a time period when injecting a delay command.
