  • Overview
    OptiNet is a sophisticated utility that tweak your system settings to boost the speed of your network and internet connection. OptiNet customize the optimizations according to the operating system you are running and the connection type. This provides added speed to your Internet load times and adds application speed and stability. OptiNet was designed to help your computer get the most out of its internet connection. OptiNet is 100% FREE.

  • Using OptiNet
    Using OptiNet is VERY simple. Run the program and then click on the Apply button for the optimization be applied. You may need to restart the computer for the changes to take effect.
    Note that optimization may not work with all ISP configurations, in which case click on the Restore button to restore the system settings.


  • How does OptiNet optimize the connection?
    By default Windows hard codes the values of many registry parameters to predefined values. OptiNet takes under account your network type, operating system and more and optimize the registry settings according to your system.

  • Registry settings for advanced users
    OptiNet takes under account several parameters such as your network type, speed, operating system and more before it optimizes registry settings. Here is a short explanation of some of the parameters OptiNet optimize:

    MTU stands for Maximum Transmission Unit and in basic terms, it defines the maximum size of a packet that can be transferred in one frame over a network.

    MSS or Maximum Segment Size defines how much actual data can put in that packet, and it is therefore a marginally smaller value than MTU to allow for packet addressing and other information.

    By default Windows hard codes the value of MTU to equal 1500 bytes. This value is adequate for normal LAN networking, but when your connecting to the Internet with a modem this value is too high. This can show itself in different ways, the most noticeable affect is less than peak performance.

    DefaultTTL Specifies the default time to live (TTL) for TCP/IP packets.

    DefaultRcvWindow Specifies the default receive window advertised by the TCP/IP stack.

    PMTUBlackHoleDetect Specifies whether the stack will attempt to detect Maximum Transmission Unit (MTU) routers that do not send back ICMP fragmentation-needed messages.

    PMTUDiscovery Specifies whether the TCP/IP stack will attempt to perform path MTU discovery as specified in RFC 1191.

    SackOpts Enables support for selective acknowledgements as documented by Request for Comment (RFC) 2018.

    Tcp1323Opts Controls RFC 1323 time stamps and window scaling options.

    EnablePMTUBHDetect Specifies whether the stack will attempt to detect Maximum Transmission Unit (MTU) routers that do not send back ICMP fragmentation-needed messages.

    EnablePMTUDiscovery Specifies whether the TCP/IP stack will attempt to perform path MTU discovery as specified in RFC 1191.

    GlobalMaxTcpWindowSize Specifies the system maximum receive window size advertised by the TCP/IP stack.

    TcpMaxDupAcks Determines the number of duplicate ACKs that must be received for the same sequence number of sent data before "fast retransmit" is triggered.
