Haven't got the answer, sorry. Compression scheme wasn't specified. * My general use is '-8086 -best' * Ruxgulo mentions '-ultra-brute -lzma -8086' * Whichever options Mike used is unclear, maybe indeed equal added decompression time (despite lowered read time). Not sure if the decompression is caused by limited CPU power, limited amount of memory, bandwidth, or whatever. ------------------------------------------------------------------------------ Got Input?
