COMPRESS={ YES | NO | RLE | LZ | ZLIB1 - ZLIB9}

You can use this parameter to specify whether to use data compression, or specify the data compression algorithm to use.

Use COMPRESS=NO on high-speed links because compression actually slows down file transfer speeds. Use COMPRESS=YES when sending data over slow-speed links (speeds of T1 and below).
