... in one of my earlier posts, it was shown that running awk to count lines was actually slower than running a "grep-wc" combination ... try this one if it's any quicker ... sometimes speed is achieved just by using the tools at hand properly ...
Code:
#! /bin/ksh

E01=`grep -c 0x00000001 errores.log`
E0B=`grep -c 0x0000000B errores.log`
E45=`grep -c 0x00000045 errores.log`
E58=`grep -c 0x00000058 errores.log`
E64=`grep -c 0x00000064 errores.log`
E66=`grep -c 0x00000066 errores.log`
TOTAL=`expr $E01 + $E0B + $E45 + $E58 + $E64 + $E66`

echo "Errores 0x01 $E01" > class_total
echo "Errores 0x0B $E0B" >> class_total
echo "Errores 0x45 $E45" >> class_total
echo "Errores 0x58 $E58" >> class_total
echo "Errores 0x64 $E64" >> class_total
echo "Errores 0x66 $E66" >> class_total
echo "T O T A L $TOTAL" >> class_total

exit 0

zegrep

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME

     zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files

SYNOPSIS

     zgrep [grep-flags] [--] pattern [files ...]

     zegrep [grep-flags] [--] pattern [file ...]

     zfgrep [grep-flags] [--] pattern [file ...]

DESCRIPTION

     zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1).

     The grep-flags and pattern arguments are passed on to grep(1).  If an -e flag is found in the grep-flags, zgrep will not look for a pattern
     argument.

     zegrep calls egrep(1), while zfgrep calls fgrep(1).

EXIT STATUS

     In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.

SEE ALSO

     egrep(1), fgrep(1), grep(1), gzip(1), zcat(1)
