Subject: Fastest way to do this?

I am using 1.6.6 <-- was this the version that did have the slow 
file problem?

# create a file to append data found from the input file
logfile = File.open(ARGV[1], "w+")

# search for a word and print the entire line
File.open(ARGV[0]) { |file|
  file.each_line { |line|
    if /jabberwock/i =~ line  	# keywords to search for
       print line		# let the lines print to console
       logfile.write line	# also print to file
    end
  }
}

# visual clue script is done
puts "Finished processing file..."

I have a Python script that does the same thing but is about 10 times faster.
