Hello, I am using a WHILE(1) that is used by the script to poll a ip address/port continously but we do not like that it is using 100% CPU. Is ther anthing that can be done as this script needs to poll 24/7. We were thinking about using the sleep but were afraid we would lose transactions. Does nyone have any ideas on modifying the script to not use 100% CPU%? Here is the part of the script with the WHILE: 
while (1) { # Continously Listening on Port for connections
    
   my ($rh_set) = IO::Select->select($read_set, undef, undef, 0);
   foreach $rh (@$rh_set) {
           print "Process each handle...\n";
           print "Main socket connection..\n";
           $ns = $rh->accept();
           $read_set->add($ns);
        }else{
              print "Ordinary socket, read...\n";
              my $bytecount = sysread($rh, $buf, 1024);
              $iroam_req_type = substr($buf,0,8);  
           
              if($buf) {
                 print " *** BEGIN PROCESSING CALL ***";
                 print "Iroam transaction received:\n";
                   print "$buf\n";
                 if ($iroam_req_type  =~ /FindMin/){              
                     $find_min_request_rec = $buf;
                 }elsif ($iroam_req_type  =~ /PriceCal/){
                         $price_call_rec = $buf;     
                 }
                  
                 pass_transaction_to_iroam_package();
                 print "Sending Response....\n";
                 $rh->send($iroam_response_rec);
             }else { 
                  print "Iroam client closed socket..\n";
                  $read_set->remove($rh);
                  close($rh);
             }
        }
    }
