Able Search can increase the speed of your Internet, so downloading files and use of the network will be much faster.

Unfortunately, default Windows settings do not guarantee the maximum possible speed of your modem, network card and software using the Internet.

Click in Able Search Tools -> Increase Internet Speed.

If you have Windows XP, click  Ping, and then OK.

Able Search Manager uses hidden Windows settings to speed up network connections. Depending on your operating system you can set different options. The best way is to select the recommended values and click OK. In Windows Vista you need administrator privileges to change some settings.

For interested persons, here is the description of each option.

DNS (Domain Name System) is responsible for translating "normal" Internet addresses to IP numbers. Each server on the network has its own unique IP address (e.g., 123.245.167.208). When you want to connect to a server such as wikipedia.org, first your computer must find on the Internet the IP number of Wikipedia. Then sending and receiving data works only with the IP number. Domain names are only for the convenience of people (not to remember and enter IP numbers), while communication between computers on the Internet is based on IP numbers.

You can set several options for handling DNS service in Windows.

- Cache size - to make it work faster, Windows for a while remembers IP numbers and corresponding domains.

- Speed

- Cache failed lookups - if Windows cannot find an IP number of a server, the browser shows known message:

Internet Explorer cannot display the webpage

If Windows stores this DNS error, then after refreshing the web page, the same error message appears. If you disable Cache failed lookups, Windows tries to re-read the server’s IP number and in case of success opens the required page.

Clear Cache - sometimes Windows collects errors in DNS cache and you cannot connect to any server. Then you can try to repair the network connection or clear the DNS.

HTTP connections - maximum number of simultaneous connections to a HTTP server. The default value (2) is usually too small nowadays, and you should increase it to 4 or 8. Too large value is not recommended.

 

Time to live (TTL) determines the maximum number of hops between routers in the network. When you send or download data from a server, you rather never connect to it directly. Data is transferred between successive computers (routers) on the Internet. If the number of routers along the way exceeds the TTL value, a data transmission error occurs. Too big TTL slows downloading pages and files from the Internet. Too small TTL value causes frequent errors.

Auto detect MTU - data on the Internet are sent in small portions, called frames. Maximum Transmission Unit (MTU) depends on the router, which sends your data. When your computer tries to send larger data packets, they are divided into frames, what slows down the transfer. Too small frames also are not optimal. To obtain the highest network connection speed, it is best to use the maximum allowed MTU value. Enable Auto detect MTU options to let Windows detect MTU and adjust to it.

Find best value - click this button if you want to check what is the MTU value for your network connection.

TCP window size - sets the maximum amount of data that a server can send to us without any confirmation. The higher Internet connection speed, the bigger TCP window you can set. Able Search Manager automatically calculates and provides the best value, which ensures fastest data transfer.

AFD buffer size. Windows NT has an additional network layer - AFD (Ancillary Function Driver for Winsock), managed by the driver AFD.SYS. To increase data transmission speed, it is recommended to increase AFD buffer size to 1024.

Send Threshold and Receive Threshold determine the threshold of data packet size, that is placed on the TCP stack or sent immediately. Datagrams with size exceeding a specified threshold are sent with a large delay. Please select the recommended value.

SACK (selective acknowledgement) means confirmation of only part of the packets sent in TCP/IP protocol. This increases transfer speed, while maintaining consistency of data.

Remote task scheduler - Windows enables remote computer control over the network and remote tasks execution (running programs, services, etc.). 99% of the average users does not use these features, which besides can be dangerous. In addition, enabled remote functions slow down network browsing even tens of seconds. To save time, it is best to disable this feature.

Most of the settings are the same as in Windows XP - they are described above.

Max Retransmissions - this option specifies how many times TCP protocol should retry to send a data when errors occur.

NetDMA allows Direct Memory Access on the network card. Thanks to it, the CPU is less loaded and the data transfer is faster.

Syn Attack Protect - enable this option to protect your computer against SYN flood attacks from the Internet. However it is better to install a personal firewall.

Compound TCP - enable this option to allow Windows automatically detect and adjust to the available size of the TCP window.

Explicit Congestion - if you have a fast Internet connection, turn off this feature.

Receive-side Scaling - accelerates the network speed on computers with several processors or multi-core processor. Data traffic processing is distributed among processors, which significantly accelerates data transmission and relieves other programs.

TCP Chimney Offload - modern network cards can perform many operations, which typically performs main CPU processor - like graphics accelerators. Windows Vista allows you to move part of the calculation to the network adapter, so the CPU is less loaded and other programs may run faster.

You must have administrator privileges to change some options in Windows Vista.

Dial-Up adapter - choose which network card you wish to optimize.

Maximum transfer unit (MTU) is described above.

I use Windows 95 without MS Dial-Up Networking 1.3 - check this option if you use Windows 95 without upgrade. It is recommended to download and install it from Microsoft Web Site.

MTU - maximum transfer unit - You can select the default value (1500), PPP (576) used mainly by phone connections, the value for Ethernet (1500), or SLIP (1006), and also provide another MTU value.

IPMTU - this is another name for MTU used in older operating systems.

You can set the MTU to the default, PPP (576), Ethernet (1500), SLIP (1006), or other.

Click Find best value - to find the optimal MTU for your network connection.

Receive window (RWIN) - specifies the number of bytes that can be transmitted at one time. Then, the sender is waiting for confirmation.

You can choose the default recommended value - calculated automatically by Able Search, or another.

You can also set time to live value (TTL), described above.

NetBeui Buffer Size - the size in kilobytes of the low-level cache for NetBEUI protocol.

COM port boost time - specifies how often (in milliseconds) the COM ports are served. Typically, modems are connected to COM ports, so a short COM handling time provides faster data transfer..

default (4) - default system value.

faster, but risky (1) - a low value could cause e.g. incorrect keyboard operation while using dial-up connection.

other - you can try 2 or 3 milliseconds.

Slownet - reduce timeouts (recommended) - this parameter rather does not accelerate the transfer, but reduces delays.

Able Search Manager can automatically find the optimal MTU value, guaranteeing a faster transfer of a modem, Ethernet adapter, etc. Click Find best value button.

Ping this host - type in an address here. A data PING packet will be sent to this server to determine the optimal MTU.

Maximal tested MTU value - enter the largest MTU value that should be tested. If Able Search will not find the best MTU, you can increase this value.

Ping - click this button to find the optimal MTU, sending PING request to the selected server. Note: You must be connected to the Internet.

Cancel - click this button to stop pinging.

Status - here you can view the current state of searching MTU.

Best MTU found - MTU value, guaranteeing the best performance. If Able Search could not find this value, select another server or increase the Maximal tested MTU value.
