title: Small file / Vs Big File Transfer Speeds
body: <p>Can anyone explain to me why I am able to achieve a higher transfer speed over my network with a 1158KB file compared to a 256KB file? Basically i'm looking into packet performance and the speeds achieved with different file sizes. If I send the small file with a packet size of 4096 Bytes, I achieve a transfer speed of 196.85 KB/s, but with the larger file, using the same packet size, i achieve a transfer speed of 951.48KB/s. What is the reason for such a difference? Is it just due to the larger file spending longer on the wire and being able to 'gather speed' as it were? </p>
  
  <p>Update : In response to one users question, protocol is UDP and a Local network. Two computers with gigabit NIC's connected by a gigabit switch. Measuring speed with a custom java program to measure speed in response to packet size change. </p>
