Windows 95 Registry Settings
For the Windows 95 user, the first step to consider is updating your Winsock2 software. Microsoft claims that this software enhancement will support large receive windows, among other items. You can get the software here.
Once the upgraded Winsock software is in place, you can use the Windows 98 tweaking information provided in Windows 98 Registry Settings.
If you choose NOT to upgrade your winsock software, there are still a few tweaks that can be implemented:
Setting MTU
Start regedit and open the following key:
HKEY_LOCAL_MACHINE --> System --> CurrentControlSet --> Services --> Class --> NetTrans --> 000n
You will see the "TCP/IP" Protocol list in the DriverDesc value as well as other identifying information about your network drivers. You will be adding a new value to this key.
- Make sure you have the correct key selected.
- Using the Edit pull-down (or right click menu), select Edit -> New String Value
- New Value #1 will appear the name of the value.
- The value should be highlighted for you to name it. Otherwise, Select Edit -> Rename. Type "MaxMTU" as the name of the value.
- Double-click MaxMTU and type "1500" in the value data box
Note: speedguide.net notes that if your are a DSL user and your ISP uses PPPoE (Point-to-Point protocol over Ethernet), you should set your MaxMTU value to 1492 or less. Other sources say to use 1500 if your connection exceeds 128k. We have not tested this with PPoE so don't have a recommendation.
Setting the Receive Window
Setting the following values may require you to experiment with the best value for your system. To set the parameters associated with the Receive Window, locate the following key: HKEY_LOCAL_MACHINE --> System --> CurrentControlSet --> Services --> VxD --> MSTCP
As in the previous step, you will provide the variable names and values for the MSTCP key. Please take special care to use the correct variable type when defining a new value pair. These are the values you will be defining:
DefaultRCVWindow="64240" Type: DWORD Decimal Variable
This string is a multiple of MSS. The range for Win95 without the Winsock2 patch is 0 - 65535. Recommended settings are 64240, 46720, 32120, 17520, 11680. Make sure you click on Decimal value and NOT Hexidecimal. Click here for a picture
PMTUDiscovery="1" Type: String Value
This value is a Boolean (true/false) variable. Set to 1, it will discover the fastest transfer speed it can negotiate, a setting of 0 will send fixed 1500 (MaxMTU) packets.
