tar is normally screaming fast unless you use bzip2 compression (or gzip compression on an underpowered CPU).
Provide details: What are you tarring, how are you invoking tar, what hardware are you running on (hard drive types, cpu type, etc).
Thanks, Jerry, I was in fact using bzip2: $ tar -cjf dcl-2010-12-07.tbz dcl-2010-12-07/
bzip2 will slow down the operation. If you don't really need compressed than simply do "tar cf <tar file> <dir/file list>"
It would be interesting to see how compression would do if pushing across a slow link :).
There are many times where I run across the OP's scenario, but often I need to push a tar across a relatively slow link. bzip is slower to compress, but may make up the difference in transfer time. Maybe time to fire up maxima and find that sweet spot :D
