An interesting question! I used the following script for "benchmarking":

> $ cat ./100_jed
#!/bin/sh
for i in `seq 100`
do jed -batch > /dev/null
done


Without precompiled library files, I get the following times:

> $ for i in `seq 5`; do /usr/bin/time -f "elapsed: %e  user: %U  system: %S" ./100_jed; done
elapsed: 0.99  user: 0.81  system: 0.17
elapsed: 0.95  user: 0.78  system: 0.17
elapsed: 0.93  user: 0.77  system: 0.16
elapsed: 0.96  user: 0.79  system: 0.17
elapsed: 0.92  user: 0.76  system: 0.16


After running

> $ jed -batch -n -l preparse 

I get slightly shorter times (~1.5 ms per single jed startup):

> $ for i in `seq 5`; do /usr/bin/time -f "elapsed: %e  user: %U  system: %S" ./100_jed; done
elapsed: 0.85  user: 0.66  system: 0.18
elapsed: 0.80  user: 0.62  system: 0.17
elapsed: 0.78  user: 0.61  system: 0.17
elapsed: 0.79  user: 0.61  system: 0.17
elapsed: 0.79  user: 0.62  system: 0.17


So yes, I can see a difference... ;-)
But is it worth the effort? Maybe not...

Cheers,

Manfred
