Hi, thank you for reply.
It's the same machine (P4) that had XP sp3 (32bit), and now run with only ubunto server (without X... and I don't want install WINE).
product: Intel(R) Pentium(R) 4 CPU 2.66GHz
vendor: Intel Corp.
size: 2700MHz
width: 32 bits
ram: 1.5gb
The vb6 prog was a simple .bas service and was very fast.
The bash conversion that I made is very fast everywhere but in loops menthioned is damn slow. Same machine.

Mmm I'm newbie in Linux, do you suggest rewrite the entire script in some else? 
What could I use that is already installed in ubuntu-server? ..and preferably that allows me to import a little 'bash code already written?
NOTE: I had try now to remove all math expression/logic code inside each (5) loops present in the script. Execution time it's now about 5 secs!
