How to Increase the Buffer in Putty

by Bonnie Conrad

Putty is an open source program that allows users to connect to servers, mainframe computers and other clients. When you open Putty and create a new session, the program uses its built-in default settings to create the connection. However, in some cases those defaults are not adequate, and changing them can improve the performance of your terminal emulation session. For instance, increasing the number of buffers in a Putty session can help the program operate more efficiently.

Open Putty. Click "Category" and then "Session."

Choose "Default Settings" and then "Load." Click "Category" and then "Session." Choose "SSH" as the default protocol.

Click "Category" and then "Window." Clear the check box next to "Reset Scrollback on Display Activity."

Go to "Category" and then "Window." Find the "Lines of Scrollback" setting from 200 to at least 20,000. Increasing the buffer setting allows Putty to perform faster and more efficiently.
