NAME
    Thrift::XS - Faster Thrift binary protocol encoding and decoding

SYNOPSIS
        use Thrift;
        use Thrift::Socket;
        use Thrift::FramedTransport;
        use Thrift::XS::BinaryProtocol;
        use MyThriftInterface;
    
        my $socket    = Thrift::Socket->new( $host, $port );
        my $transport = Thrift::FramedTransport->new($socket);
        my $protocol  = Thrift::XS::BinaryProtocol->new($transport);
        my $client    = MyThriftInterface->new($protocol);
    
        $transport->open;
    
        $client->api_call( @args );

DESCRIPTION
    Thrift::XS provides faster versions of Thrift::BinaryProtocol and
    Thrift::MemoryBuffer.

    Thrift compact protocol support is also available, just replace
    Thrift::XS::BinaryProtocol with Thrift::XS::CompactProtocol.

    To use, simply replace your Thrift initialization code with the
    appropriate Thrift::XS version.

SPEED
    For the best performance, you need to use a custom socket layer and both
    Thrift::XS::MemoryBuffer and one of Thrift::XS::BinaryProtocol or
    Thrift::XS::CompactProtocol. If using the standard BufferedTransport,
    FramedTransport, or HttpClient modules, performance will not be as good
    as it could be. In particular, HttpClient is incredibly bad, making a
    lot of very small (1-4 byte) sysread() and print() calls. A future
    version of this module will probably provide XS implementations of these
    other modules to help with this problem.

    Here is a breakdown of the performance improvements of the various
    low-level methods. A given Thrift API call will make many write and read
    method calls, so your results will be some average of these numbers. For
    detailed numbers and to run your own benchmarks, see the bench/bench.pl
    script.
