DETuning low-level network settings

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 Desktop Client Konfigurationsdateien:

# 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
