Data compression and decompression methods for compressing and decompressing data based on an actual or expected throughput (bandwidth) of a system. In one embodiment, a controller tracks and monitors the throughput (data storage and retrieval) of a data compression system and generates control signals to enable/disable different compression algorithms when, e.g., a bottleneck occurs so as to increase the throughput and eliminate the bottleneck.

The method of claim 1, further comprising: selecting the one or more compressors to compress the at least the portion of the data block to create at least a second compressed data block based upon a number of reads of at least a portion of a first compressed data block that was created from the at least the portion of the data block. 9. The method of claim 1, wherein the determining of the parameter or attribute of the at least the portion of the data block excludes determining based only upon reading a descriptor of the at least the portion of the data block. 10. The method of claim 1, wherein the at least the portion of the data block is from among a plurality of data blocks; and wherein the compressing comprises: compressing at least a portion of the plurality of data blocks with the one or more compressors using the asymmetric data compression and the information to create the one or more compressed data blocks. 11. The method of claim 10, wherein the plurality of data blocks or the one or more compressed data blocks comprise: at least a portion of a file. 12. The method of claim 1, wherein the compressing comprises: compressing the at least the portion of the data block with the selected one or more asymmetric compressors to create one or more portions of the one or more compressed data blocks, the at least the portion of the data block having been compressed with the selected one or more asymmetric compressors to create the one or more portions of the one or more compressed data blocks, and further comprising:storing at least the one or more portions of the one or more compressed data blocks. 13. The method of claim 12, further comprising: retrieving at least a portion of the at least stored one or more portions of the one or more compressed data blocks;transmitting the at least retrieved portion of the at least stored one or more portions of the one or more compressed data blocks over the Internet; anddecompressing the at least transmitted portion of the at least stored one or more portions of the one or more compressed data blocks in real-time. 14. A method, comprising: determining a parameter or attribute of at least a portion of a data block;selecting an access profile from among a plurality of access profiles based upon the determined parameter or attribute; andcompressing the at least the portion of the data block with one or more compressors utilizing information from the selected access profile to create one or more compressed data blocks, the information being indicative of the one or more compressors to apply to the at least the portion of the data block,wherein the one or more compressors utilize at least one slow compress encoder and at least one fast decompress decoder, andwherein compressing the at least the portion of the data block with the at least one slow compress encoder takes more time than decompressing the at least the portion of the data block with the at least one fast decompress decoder if the time were measured with the at least one slow compress encoder and the at least one fast decompress decoder running individually on a common host system. 15.
