Well, for this case you shouldn't simply pick one or the other. Again, on Linux, you generally can't use /dev/random at all -- it will block after reading just a few dozen bytes. /dev/urandom won't block, but your suggestion of creating a large file from it is very sensible. /dev/urandom seems to measure about 3MB/sec or thereabouts, so creating a large "uncompressible" file could be done sort of like: dd if=/dev/urandom of=tempchunk count=1048576 cat tempchunk tempchunk tempchunk tempchunk tempchunk tempchunk > bigfile -- Henry Yen Aegis Information Systems, Inc.
