TCP-Z

TCP-Z is a tiny application that allows users to monitor the network traffic and to limit the number of half-open TCP (Transmission Control Protocol) connections to one’s computer. Beginners are advised to steer clear of this app or ask for professional help before modifying any network settings (rather than boost the performance, they might end up slowing it down).

The software utility comes with an intuitive interface that allows users to choose the network adapter they want to monitor, as well as analyze the current traffic data (both the download and upload details are logged).

TCP-Z features a Statistics module, so that users can continuously monitor data such as outgoing connection attempts or successfully established connections, along with network adapter information.

Those who like to always be in control of the resource usage on their PC can rely on TCP-Z to explore how much RAM each running program is taking up - this way, they can terminate resource hogs before they crash the host PC.

When it comes to removing or increasing the limit of TCP connections, users need to take extra care in their attempt to boost downloads’ speed or the overall performance of their network connection. All changes can be applied instantly, and the settings are reset to the default values once the computer is rebooted.

Another aspect that needs to be taken into consideration is the fact that users running x64 platforms might encounter errors when it comes to launching and using TCP-Z, as well as those who have enabled UAC on their PC. Instructions for successfully deploying the app can be found in the documentation files, and they refer to running the driver in a testing mode.
