Do I need a bigger swap area? Use system tools like systat, vmstat, top, ps, etc to see what's going on. If you're trying to run more processes than will fit in memory, then you'll experience the kinds of delays you experience. Even if the machines aren't constantly loaded, if a transient job allocates a lot of memory it will push to swap other inactive things like inetd, telnetd, samba, etc, which then take a while to read back in the next time they're used. Consider adding more RAM if it's a problem.
