Illuminatus, yes that is in fact what I am mostly worried about. In fact I think the Mem Usage here is due to one of the threads doing a regex replace, adding backslashes to prepare a file to be imported into mysql.

Edit: Just to clarify, I know that the CPU use should also be high when doing a regex on a large file with many matches, however, the CPU usage of the perl.exe process is always high, even when no regex operations are being performed.

My do_handler function just routes the work to a function in the separate Worker module (I couldn't figure out the syntax to call it directly)

Here's the relevant code from the Worker module:
package File::FileListerWorker; sub main_run { # arguments: 1) job id from Pooler 2) path to scan 3) Path to FileLi +st.exe 4)table name # returns: 1) return 1; #### - START: MAIN EXECUTABLE CODEBLOCK - #### my $jobid = shift; # read scanpaths from the ARGs my $scanpaths_line = shift; # get path to scan my $fl_path = shift; # define path to FileList.exe my $arg_tbl_name = shift; # table to load data into my $dbh = &mysql_conn(); # connect to mysql my $mysql_tablename = &mysql_create_table( $arg_tbl_name, $dbh ); +# create table (IF NOT EXISTS) my @ta = localtime(time); # get time my $time_string = $ta[4] . $ta[3] . ( $ta[5] + 1900 ) . "_" . $ta[2] . $ta[1] . $t +a[0]; # time string my $temp_filename = # make unique filename "\\\\directoryToPlaceTempFileIn\\" . $jobid . "_" . $time_string . ".csv"; &do_scan( $fl_path, $scanpaths_line, $temp_filename ); # call to s +ub that does the scan my $mysql_temp_filename = &fix_file_4mysql($temp_filename); # add +backslashes &mysql_load_data( $mysql_temp_filename, $mysql_tablename, $dbh ); +# mysql import file &cleanup($temp_filename); #delete temp file to preserve space &mysql_disc($dbh); # disconnect mysql #### - END: MAIN EXECUTABLE CODEBLOCK - #### return 1; } sub do_scan { #arguments: 1)location of FileList.exe 2)path to scan 3)output fi +le path #returns: none my $fl_path = shift; my $pth = shift; chomp($pth); my $temp_filename = shift; system(qq{$fl_path $pth >$temp_filename}); }
