Splitting into more or less files wouldn't change the actual amount of work. If anything, bigger files and fewer loops would be more efficient -- awk is at its most efficient when you give it a big job and let it do its thing, instead of restarting it for tiny jobs all the time.

It's not like it's keeping those 10,000 lines around in memory anyway, nothing's getting overloaded. (And even if it were, 10,000 lines is not a lot for awk!)

Your specific description doesn't tell me much about anything except how big your files are, you haven't told me what you will be doing with them.

Temporary(4)						     Kernel Interfaces Manual						      Temporary(4)

NAME

       Temporary - Stores data files during transfers to remote systems

SYNOPSIS

       /usr/spool/uucp/SystemName/TM.xxPID.000

DESCRIPTION

       The  uucp  Temporary  (TM.*) files store data files during transfers to remote systems.	After a Data (D.*) file is transferred to a remote
       system by the uucico daemon, the uucp program places it in a subdirectory of the uucp spooling directory named  /usr/spool/uucp/SystemName,
       where  the SystemName directory is named for the computer that is transmitting the file.  The uucp program creates a temporary data file to
       hold the original data file.

       The full pathname of the temporary data file is in the following format: /usr/spool/uucp/SystemName/TM.xxPID.000

       where the SystemName directory is named for the computer that is sending the file, and TM.xxPID.000 is the name of the file;  for  example,
       TM.00451.000.  The PID variable is the process ID of the job.

FILES

       Describes accessible remote systems Contains uucp command, data, and execute files Contain data to be transferred.  Contain files that uucp
       has transferred
