Apparently the repeated string concatenation and word splitting was much slower. While at it, also remember in $ZFCP_UNIT_PATH whether the loop over ZFCP_UNIT_ARRAY already found a zfcp_unit and re-use the path string to replace the previous file glob construct generating the zfcp_unit path by means of pathname expansion. This only works for the extended output case.
