You invoke an external program 10 times for every record - that's why it is slow

try something like this:
Code:
awk ' {
printf("%s|%s|%s|%s|%s|%s|%s|%s|%s|%s\n",
      substr($0,1,5) ,
      substr($0,6,4) ,
      substr($0,10,2),
      substr($0,12,3),
      substr($0,15,1),
      substr($0,16,2),
      substr($0,18,5),
      substr($0,23,1),
      substr($0,24,1),
      substr($0,25,1) ) } ' infile.txt > outfile.txt
