WHAT DOES window size indicate?
When the receiver sends an acknowledgment, it will tell the sender how much data it can transmit before the receiver will send an acknowledgment. We call this the window size. Basically, the window size indicates the size of the receive buffer.
How does TCP window size improve network performance?
On Cisco devices, you can adjust the the window size using the global configuration command, “ip tcp window-size”. This command only affects sessions to the Cisco device itself. Network devices generally won’t change the parameters for sessions that merely pass through them.
What does the TCP window size control?
The TCP window size field controls the flow of data and is limited to 2 bytes, or a window size of 65,535 bytes. Since the size field can’t be expanded, a scaling factor is used. TCP window scale is an option used to increase the maximum window size from 65,535 bytes to 1 Gigabyte.
Why is Windows file transfer so slow?
So what is the culprit that slows down the file copy? The most common causes include disk fragmentation, file system errors, outdated drivers, antivirus settings, and some other Windows features. If you want to copy an entire hard drive, it’s also recommended to use its powerful disk cloning feature.
How can I increase my small transfer speed?
Potentially the only way to speed it up is to zip the files up into one file, copy the file across the network, unzip the files at the end. Ironically it is faster…. Agree, zip it up,or put it on a VHD and block level copy rather than all those single files of you can.
What is the difference between MTU and window size?
