Since TCP packets have a 40 byte header (20 bytes for TCP, 20 bytes for IPv4), this results in a 41 byte packet for 1 byte of useful information, a huge overhead. Nagle’s document, Congestion Control in IP/TCP Internetworks (RFC896) describes what he called the ‘small packet problem’, where an application repeatedly emits data in small chunks, frequently only 1 byte in size. Nagle’s algorithm, named after John Nagle, is a means of improving the efficiency of TCP/IP networks by reducing the number of packets that need to be sent over the network. For example, when logging at high speed or pasting large configurations to your console (there are many other criteria that affect this, but this is one of them). Nagle’s algorithm is particularly useful when attempting to transfer a lot of information in the terminal.

With that many windows you need a way to tell them apart, thus, some names on the box would be useful in identifying. It’s common for me to have more than ten putty sessions open at a single time. Cleartype Font Aliasing Window Names/Title Less reading errors results in better work performance. The choice to use Antialiased or aliased fonts is a bit complicated, but its a serious decision affecting how easy on the eyes ad how quickly you can read the screen. Setting the SCROLLBACK to 20000 lines Using Font Aliasing Making it too large may impact your computer by reducing the amount of memory available. Note that every Putty session will allocate a block of memory sufficient to hold those lines in a buffer. See IOS – Setting the Terminal Windows Length for a good-ish description of this. If you change the Windows Rows to forty, then you should also change your device terminal settings to use forty lines as well. And since most screens allows more than 25 rows, I would increase the Window Rows to forty. Typically I would set the default to be 20000 lines. For a typical network engineer, this isn’t enough to show the configuration, must less any decent amount of text. Set the Rows & Scrollback Linesīy default Putty only keeps the last 200 lines of text displayed on your screen in the scrollback buffer. Not many people seems to realise that Putty is highly customisable and has a number of features that will improve your working environment. ((After all, Microsoft doesn’t supply any SSH in Windows or even telnet capability in Vista)).
