Abstract
An invention is provided for filtering cached input/output (I/O) data. The invention includes receiving a current I/O transfer. Embodiments of the present invention evaluate whether to filter ongoing data streams once the data stream reaches are particular size threshold. The current I/O transfer is part of an ongoing sequential data stream and the total data transferred as part of the ongoing sequential data stream is greater than the predetermined threshold. The transfer rate for the ongoing sequential data stream then is calculated and a determination is made as to whether the transfer rate is greater than a throughput associated with a target storage device. The current I/O transfer is cached when the transfer rate is greater than the throughput associated with a target storage device, or is not cached when the transfer rate is not greater than the throughput associated with a target storage device.
