I doubt that, let's see:

  $ time sh -c 'seq 1 1 | xargs -n 1 gpg --version >/dev/null'
  
  real    0m0.010s
  user    0m0.004s
  sys     0m0.004s
  $ time sh -c 'seq 1 100 | xargs -n 1 gpg --version >/dev/null'
  
  real    0m0.361s
  user    0m0.068s
  sys     0m0.024s

This is less than 4ms per exec.  So you problem is for sure not the
fork/exec.


Salam-Shalom,

   Werner
