BASH Slow Under Cron Only!

I've got a BASH script that runs much faster from the command line than when invoked under CRON.

Ideas? Priority? IO?

Please post:

  1. the script (or something that exhibits the same behavior)
  2. crontab entry

As an offhand guess - it relates to environment variables - for about 90% of cron jobs that have problems the issues are largely environment.
