MaxFreeTcbs regedit tweak

MaxFreeTcbs determines how many active TCP connections your computer can handle at any given time based on how much physical memory you have and how much performance your computer has with regard to bandwidth.

If the number is too high, your computer may not properly process TCP transactions because of the high amount of active connections talking to the computer at the same time. However, if the number is too low, you can’t host or request as many connections as you’d like. While the setting is arbitrarily determined, you may want to bump up the number when you upgrade your hardware or Internet connection.

What is MaxUserPort and how to modify it

When an application requests an available port to open from Windows, the operating system chooses one port from 1024 to a specified maximum known as “MaxUserPort.” A port on your computer allows you to establish TCP/UDP connections through the Internet and in your local network. What happens when you open more options to programs seeking a port? They find a port much faster than they would with only a couple thousand available choices.

Windows sets this value to 5000 by default, but you can set it up for any number from 5000 to 65534.

How to modify GlobalMaxTcpWindowSize for better upload speeds

This value has a long name, but you won’t regret modifying it if you have a big Internet connection (10 Mbps and up) and often upload stuff. This value represents how much data can be sent from your computer without receiving an acknowledgement (ACK) packet.

Every time you send small chunks of data on the Internet, your computer has to wait for this packet, which tells your end of the network, “Everything’s OK! Send more!” Sometimes, due to latency and poor peering, this might not be ideal. So, you can edit this value to allow more data to be sent without waiting for that packet to come.

How to modify DefaultTTL using regedit

Time to Live (TTL) tells routers how long a packet should stay in the air while attempting delivery before giving up and discarding the packet. When the value is often high, your computer spends more time waiting for a failed packet to deliver, effectively decreasing the amount of productivity in your network.

Without a value set, Windows waits 128 seconds for the transaction to finish. This makes your computer lag terribly if you’re in the middle of something and your connection with a server unexpectedly goes south.

Increase network speed by modifying SizReqBuf

SizReqBuf represents the size of the raw receive buffers within a server environment. This means it will affect your ability to host something in a high-latency environment. Let’s say you host a game server and tons of people complain about lag. Modifying this value will help reduce the impact of lag. You’d also benefit if you’re hosting a website or any other service, including sending files through instant messenger or Neo Modus Direct Connect.

Your system usually places this buffer at 16384 bytes. For most servers, this is efficient enough, but sometimes you have a small amount of memory and cannot keep up with the high request volume.

How to Automatically Delete Pagefile on Shutdown in Windows 10

Pagefile.sys acts as a virtual RAM, which Windows uses as RAM to store programs that are not in use, thus putting less pressure on the actual RAM. The page file size is usually near the size of your actual RAM, so it can take up a lot of space depending on your RAM. If you set the pagefile to delete with shutdown, you will save some hard drive space in exchange for slightly prolonging your shutdown time.

Here is one way you can get the system to automatically delete the pagefile.sys on shutdown in Windows 10.

How to Disable the Startup Delay using Regedit

By default, Windows 10 has a 10-second delay during boot before all your apps and programs become accessible. This is called the “Startup Delay,” and it helps make sure everything works as it should when you start up your PC. If, however, you have a powerful PC, or not many startup programs in Windows 10, then you can try to reduce or even disable the startup delay altogether to help your PC start up faster.
