Remember what Bruno Jargot wrote about performance and POSIX:

|s="$(echo ${s}x)" ; done'

|real 1m40.230s
|user 1m10.660s
|sys 0m7.548s
|
|$ time ksh93 -c 'i=0 ; s="" ; while [ $i -lt 10000 ] ; do i=$((i+1)) ;
|s="$(echo ${s}x)" ; done'
|
|real 0m11.947s
|user 0m8.641s
|sys 0m1.540s
|
|ksh93 is much faster (10x) and has many features like arrays which
