tr was made for that.
Code:
tr -d '($)'  < file

And here is the time test:
Code:
# time awk '{gsub("[($)]","",$0)}1' file > /dev/null

real    0m0.311s
user    0m0.244s
sys     0m0.028s
# time tr -d '($)' < file > /dev/null

real    0m0.065s
user    0m0.024s
sys     0m0.004s
# time sed 's/(\|\$\|)//g' file > /dev/null

real    0m1.144s
user    0m1.092s
sys     0m0.000s
# wc file
 18000 108000 738000 file

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
