Tuning low-level network settings
This article describes how to tune low-level TCP and UDT network settings of the client to achieve higher transfer rates or to optimize the client to your network.
The settings described in this article require a basic understanding of the IP protocol stack, therefore don't use them, if you are not experienced in this regard.
We recommend to read the article about TCP Tuning on Wikipedia before proceeding.
Tuning the TCP / UDT socket buffer size
It's possibe to control the TCP send and receive buffer (SO_RCVBUF / SO_SNDBUF) adding the entries below to the Client Configuration Files:
# TCP and UDT connections net.socket.internet.buffer.size=16384 net.socket.lan.buffer.size=65536 # UDT Connections only net.socket.internet.buffer.limit=262144 net.socket.lan.buffer.limit=1048576
Tuning the chunk size and and queue
Files get transferred over the network in small packets called file chunks. These chunks contain a certain amount of data (e.g. 32KB) transferred at one to a remote device. When the client requests multiple chunks at one from the remote device stored in a queue.
Setting the maximum size of a file chunk
To control the maximum size of a chunk:
transfers.max.file.chunk.size=32768
Setting the maximum number of file chunks in the queue
To control the maximum file chunk queue size:
transfers.max.request.queued=15
