If I understand your problem, you're doing a global search and match, output conditional on that match. The reason it takes so long is that you are going through your big file for each line in your control. By the above script, you are processing "J" times for each "I". If you start by sorting your "J" records by the 7, 13 and 14 fields, then you can "ladder walk" the "I" records and the "J" records, thus only going through each list once. Your script will be done almost immediately. The "i" records must, of course, also be sorted the same way.

NAME
sysstat - sysstat configuration file. DESCRIPTION
This file is read by sa1(8) and sa2(8) shell scripts from the sysstat's set of tools. It consists of a sequence of shell variable assign- ments used to configure sysstat logging. The variables and their meanings are: HISTORY The number of days during which a daily data file or a report should be kept. Data files or reports older than this number of days will be removed by the sa2(8) shell script. COMPRESSAFTER Number of days after which daily data files are to be compressed, either by gzip or bzip2. SADC_OPTIONS Options that should be passed to sadc(8). With these options (see sadc(8) manual page), you can select some additional data which are going to be saved in daily data files. These options are used only when a new data file is created. They will be ignored with an already existing one. FILES
