Tivoli Storage Manager for Sun Solaris Administrator's Reference
Specifies, in kilobytes, the amount of receive data that can be buffered at
one time on a TCP/IP connection. The sending host cannot send more data
until it receives an acknowledgment and a TCP receive window update.
Each TCP packet contains the advertised TCP receive window on the
connection. A larger window lets the sender continue sending data, and
may improve communication performance, especially on fast networks with high
latency.
Notes:
- To improve backup performance, increase the TCPWINDOWSIZE on the
server. To improve restore performance, increase the TCPWINDOWSIZE on
the client.
- The TCP window acts as a buffer on the network. It is not related
to the TCPBUFFSIZE option nor to the send and receive buffers allocated in
client or server memory.
- A window size larger than the buffer space on the network adapter might
degrade throughput due to resending packets that were lost on the
adapter.
Syntax
>>-TCPWindowsize--kilobytes------------------------------------><
Parameters
- kilobytes
- Specifies the size you want to use, in kilobytes, for the TCP/IP sliding
window for your client node. You can specify a value from 0 to
2048. Values from 1 to 2048 indicate that the window size is in the
range of 1K to 2M.
Examples
tcpwindowsize 8
