A compressor having a dual slide valve assembly is disclosed. The slide v alve assembly includes: i) a volume slide valve mechanism that is slidably m ovable to control compressor volume ratio and power input to the compressor; and ii) a capacity and volume slide valve mechanism that is in operational association with the volume slide valve mechanism, and the capacity and volu me slide valve mechanism is slidably movable to control compressor capacity and to control volume ratio and power input to the compressor. In at least s ome embodiments, the compressor is a rotary gas compressor for a compression (e.g., refrigeration) system. A method of increasing compressor efficiency using the dual slide valve assembly is also disclosed. Compressor volume loa d and/or volume ratio and/or compressor power input can be simultaneously co ntrolled by both the volume slide mechanism and the capacity and volume slid e mechanism. Advantageously, compressor efficiency is increased.
