Sometimes a significant "first-time" delay is due to DNS reverse- lookup timeouts (if the platform's address isn't in anyone's DNS database). You might be able to check this with tcpdump or, more easily, by completely disabling networking (in both the virtual and real systems). Can you determine (e.g., with 'top') whether the delay is computational or due to a timeout (all processes just twiddling their thumbs)? Justin -- Justin C.
