About Speedy Web Navigator



General Program Usage
On loading, the program will open the DNS Optimizer screen first. To move to another screen click with the mouse on one of the blue buttons on the left.
To Exit the program you can either click on the cross in the top right corner, or click on the Exit text in the bottom right corner. Next to the cross is a flat bar, this will minimize the application to the Task bar. The question mark next to that will open the online help file (you must be connected to the internet).

Note: You cannot exit the program whilst Optimization is in progess. You have to cancel the process first.

UnRegistered Version
The unregistered Shareware version of Speedy Web Navigator is limited in various ways.

1. Only the first 25 bookmarks found will be optimized.
2. Only the first 25 Advert Banners will be blocked.
3. Only the MTU setting can be saved in the Cable/DSL/Dial-Up Modem Optimization screen.

DNS Optimizer
This is the opening screen of Speedy Web Navigator, it shows you the current status and progress.

Internet Connection
This shows whether Speedy Web Navigator has found your internet connection settings.

Browsers Found
This tells you what Internet Browsers were found on your system. These will be used for bookmark optimization. You can disable the scanning of bookmarks for a particular browser on the Options screen.

Banner Advert Blocker
This tells you whether Speedy Web Navigator will block Advert Banners. This options can be enabled or disabled from the Options screen.

Progress
This shows the current status of the Optimization. Succesful operations are marked with a tick and unsuccessful ones with a cross.

Status
This shows a text message explaining the current status of the program, or what is currently being done in the optimization process.

Go button
This starts the optimization process (bookmark and banner advert blocker only, the Dial-up optimization must be done from the Dial-Up Optimization screen.). It requires you to be connected to the Internet first. If you have unselected all browsers and not enabled the banner advert blocker then the optimizations will be removed. It is recommended that you do this first before uninstalling the application.
Once optimization is in progress the Go button changes to a Cancel button, which can be used to halt the progress and return optimizations to their previous state. It is recommended that you either reboot your computer, or reconnect and reload your Internet software, once optimization is complete. Warning: You will need to update this information on a regular basis, because some websites may change their IP address. This could result in you not being able to reach a site.


Cable/DSL/Dial Up Modem Optimizer
This screen allows you to optimize your Internet Cable/DSL/Dial-Up connection by adjusting hidden Windows settings. Although you can adjust them manually, it is not recommended unless you know what you are doing. The best technique is to use the Presets by clicking on the button with the type of connection you have to the internet, this will adjust all the settings to give you a faster Internet connection. Then click on the Save Settings button to save the changes. These changes are permanent and you normally won't have to adjust them again.

There are up to six options you can adjust:

MTU (Maximum Transfer Unit) - All Versions
Short for Maximum Transmission Unit, it is the largest physical packet size, measured in bytes, that a network can transmit. Any messages larger than the MTU are divided into smaller packets before being sent. Every network has a different MTU, which is set by the network administrator. On Windows 95, you can also set the MTU of your machine. This defines the maximum size of the packets sent from your computer onto the network. Ideally, you want the MTU to be the same as the smallest MTU of all the networks between your machine and a message's final destination. Otherwise, if your messages are larger than one of the intervening MTUs, they will get broken up (fragmented), which slows down transmission speeds.

Unset
This removes the setting and uses the Operating System default value instead. Which is 1500 for Windows 95.

Modem (576)
This is the optimal setting for Dial-up Internet connections.

Cable/DSL/LAN (1500)
This is only recommended for LAN (Local Area Network) connections or some Cable Modems.

Custom
This allows you to specify a custom MTU value. This is not recommended unless you fully understand the implications of using a non-standard value. You would look to use this option when setting DSL modems with PPoE that do not have their Maximum Segment Size at 1500.

Receive Window (RWIN) - All Versions
The TCP RWIN or Receive Window limits the number of TCP data segments the remote TCP sender can launch onto the Internet before waiting for acknowledgement of receipt signals from your much slower machine. Since you don't want the TCP sender to transmit fragments or left-overs, you should ask them for an RWIN that equals an integer number of TCP data segments.

Time To Live (TTL) - All Versions
TTL stands for Time To Live. This value specifies the number of ‘hops’ or hosts that your TCP/IP request can go through before timing out. If you have trouble connecting to hosts more than 32 hops away, you can try increasing this number to a higher value.

MTU Auto Discover - All Versions
This option enables the system to automatically determine the Maximum Transmission Unit (MTU) value and detect routers which do not return valid data. It is not recommended that you disable this setting as it can cause severe performance degradation because fragmentation may not be compensated for.

MTU Black Hole Detect - All Versions
Enabling this option allows the system to try to detect black hole routers. Black hole routers are routers that do not send back ICMP fragmentation-needed messages while automatically determining the optimal MTU value. This increases the maximum number of retransmissions performed for a given segment. Enabling this parameter when it is not needed can cause performance degradation. It is recommended that you leave this option disabled.

TCP1323 - All Versions
This option should be enabled when you set the RWIN value size greater than 64K.

SackOpts - All Versions
Selective acknowledgements allow TCP to recover from IP packet loss without resending packets that were already received by the client. This option is one of the more important options for providing stability in online gaming by being able to recover from lost packets.

MaxDupAcks - All Versions
Fast Retransmission and Fast Recovery of TCP connections that are encountering IP packet loss in the network. Allow a TCP sender to quickly infer a single packet loss by reception of duplicate acknowledgements for a previously sent and acknowledged TCP/IP packet. This mechanism is useful when the network is intermittently congested and also in conjunction with SackOpts provides even further connection stability.

Cache Good DNS Only - XP Version Only
Windows 2000/XP has built-in DNS (Domain Name System) caching, which basically caches resolved hostnames for faster access and reduced DNS lookups. This is generally a great feature, with the only downside that failed DNS lookups get cached by default as well... When a DNS lookup fails (due to temporary DNS problems), Windows still caches the unsuccessful DNS query, and in turn fails to connect to a host regardless of the fact that the DNS server might be able to handle your lookup seconds later.

Server Turbo - XP Version Only
This option enables more concurrent connections to the server being accessed on the internet. This setting is optimal when accessing high-bandwidth servers.

Options
This screen is used to change options about the DNS Optimization process.

Scan Netscape Navigator
If Netscape is found on your system, this will allow you to disable or enable the bookmark optimization for it.

Scan Internet Explorer
If Internet Explorer is found on your system, this will allow you to disable or enable the bookmark optimization for it.

Enable Banner Advert Blocker
This allows you to select or deselect banner advert servers to block. By default this option is disabled. You may want to deselect some for various reasons including:
a) Some adverts cause error messages to be displayed if they cannot be opened. b) You may want to access the server, if you run banner adverts on your website.
These settings will be saved when you close the program, but changes won't be made until you reoptimize your computer.
