Do you want to increase system performance by adjusting TCP/IP parameters?

TCP/IP performance over an ATM network can be poor unless you carefully configure your network. Poor performance usually occurs because the TCP/IP packets are segmented into cells for transmission by the ATM software. Therefore, a loss of a single cell can cause the loss of an entire TCP/IP packet which can lead to retransmissions that congest the network. When it detects congestion, the destination system reduces the transmission rate, which significantly reduces the network performance.

You can achieve better network performance from the SunATM adapter and software by adjusting your application's socket buffer size to 48 Kbytes. Refer to the application's documentation for instructions on how to set the socket buffer size.
