Increase send and receive buffer size to improve file transfer speed

Product Readmes


Abstract

For slowness in file transfers it is now being recommended that the sendBufferSize and receiveBufferSize be set to 4M in the perimeter.properties file located in the Secure Proxy engine bin directory.

socket.sendBufferSize=4M
socket.receiveBufferSize=4M
socket.setBufferSize=true

*.connection.windowSize=4M


If socket.setBufferSize is set to "false" then the buffersize (window size) from the TCP stack of the OS will be used.

After making the changes, stop and restart the engine.
