BrowserUk,

I use IO::Socket::UNIX for both the client and server. The routines are almost exactly the same as the perl documentation: Note: I typed this code in, so I doubt it will compile and this is just part of a lot of other code.

Server:

 use IO::Socket::UNIX;
 use strict;
 my $server = new IO::Socket::UNIX -> new ( Local  => "$ROOT/envSocket
+",
                                            Type   => SOCK_STREAM,
                                            Reuse  => 1,
                                            Listen => 147 );
 [ ... error handling ... ]
 while ( 1 )
 {   my $client = $server => accept();
     if ( defined $client )
     {   eval
         {  while(<$client>)
            {   $Todo .= $_; chomp($Todo); }
          }
          if ( $@ ) { ... }
          if ( $Todo ) { ... process work ... }
          close $client;
      }
 }

Client:

 use IO::Socket::UNIX;
 use strict;
 my $server = new IO::Socket::UNIX -> new ( Peer   => "$ROOT/envSocket
+",
                                            Type   => SOCK_STREAM,
                                            Timeout => 10 );
 [ ... error handling ... ]
 print $server "$Todo\n";
 shutdown ( $server, 1 );
 while ( <$server> )
 {   $answer .= $_;
 }
 shutdown ( $server, 2 );
 close $server;
 ...

 }

Even if I mistyped the code, the actual code works as expected. But the process is a lot slower than I had expected. Here are some results:

50,000 records processed:  ( results are number/second )

                              1 process | client/server
                     Writes:      2,953 | 1,152
                     ReadNext:   35,138 | 2,870
                     ReadPrev:   34,236 | 2,616

So, if I could keep a persistent connection between the server and the client then performance may be better. Everything I have tried has just hung. Some information supplied by zentara has given me some new ideas.

Any help will be greatly appreciated.

Thank you
