Systems and method provide for consistent throughput of one or more compression engines. Data received from an input stream is stored in a buffer. Data is read from the buffer and distributed to the compression engines. Latency of the compression engines is monitored. If latency exceeds a threshold, data is read from the buffer and written to an output stream simultaneously with reading of data and inputting it to the compression engines. Data from the input stream may be evaluated for likely compressibility and non-compressible data may be written to the output stream bypassing both the buffer and the compression engines.
