Optimize awk code

sample data.file:

Code:
0,mfrh_green_screen,1454687485,383934,/PROD/G/cicsmrch/sys/unikixmain.log,37M,mfrh_green_screen,28961345,0,382962--383934
0,mfrh_green_screen,1454687785,386190,/PROD/G/cicsmrch/sys/unikixmain.log,37M,mfrh_green_screen,29139568,0,383934--386190
0,mfrh_green_screen,1452858644,-684,/PROD/G/cicsmrch/sys/unikixmain.log,111M,mfrh_green_screen,732502,732502,,111849151,0,731818
0,mfrh_green_screen,1452858944,-888,/PROD/G/cicsmrch/sys/unikixmain.log,111M,mfrh_green_screen,732707,732707,,111918753,0,731819


Code i'm running against this file:

Code:
VALFOUND=1454687485
SEARCHPATT='Thu Feb 04'
awk "/,${VALFOUND},/,0" data.file | gawk -F, '{A=strftime("%a %b %d %T %Y,%s",$3);{Q=1};if((Q)&&(NF == 13)){split($4, B,"-");print B[2] "-" $3 "_0""-" $4"----"A} else if ((Q)&&(NF == 10)) {split($NF, B,"--");print B[2]-B[1] "-" $3 "_" $10"----"A}}' | egrep "${SEARCHPATT}" | awk -F"----" '{print $1}'

data.file is about 7MB in size and can grow quite bigger than that. when i run the above command on it it, it takes about 6 seconds to complete. Anyway to bring that number down???

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
