Hello list,
this is rather unusual: I want a chunk of random garbage, and I want it
fast. The background is that I have a streaming test, and to run into some
intelligent read-ahead/write-behind/caching algorithm, I need random
stuff. /dev/null is fast, but obviously won't do it. /dev/urandom is too
slow. In C, I once resorted in a similar case to using malloc() to get
some portion of memory without initializing it and writing that, but Perl
doesn't let me access malloc(), at least not via POSIX. I already tested
something like "rand x 100", but that's too slow, too. :-/
Any ideas are greatly appreciated.
Thanks in advance,
Eric

Could you use a file of random data? You can create one of those really
easy: dd if=/dev/urandom of=ranfile bs=9999
