Increasing Performance on Enterprise Servers
If you deploy four ITI-8241C-S Four-Port FastEthernet adapters in an
Enterprise Server you may experience slow performance and response times
during peak periods of high network traffic. This poor performance is
usually caused by applications that use data buffer and socket buffer sizes
greater than 8Kbytes.
Improved performance can be achieved by adjusting the application’s data
buffer size to be less than or equal to 8Kbytes.
IP Forwarding Routing Protocols
The Solaris operating system will by default configure systems with more
than one network interface to be an IP forwarding router. Installing an ITI-
8241C-S in a system will make this occur.
An Application Server which might be running a Database or NFS file
services is typically “multihomed” which means that that they contain more
than one network interface but do not run IP protocols or forward IP packets.
If IP forwarding and routing protocols on multihomed application servers is
not disabled the servers may experience poor performance.
For more information, refer to the TCP/IP and Data Communications
Administration Guide shipped with the Solaris documentation.
