Problem:
Installing an update from Microsoft has impacted Acucorp's Thin Client performance.
What can be done?
Resolution:
It is possible that the patch installed changed the TCP/IP settings. Software such as Dr.TCP or TCPOptimizer can be used to tune TCP/IP settings.
Setting the TCPReceiveWindow to 1500 on WinXP SP2 and Win2000 SP4 has proven to improve Thin Client speed when working with a Aix 5.2 5L PowerV host, along with other Unix boxes.
This setting is not intended to be the "definitive" answer, but just a start from where to begin tuning TCP (and Thin Client) performance. After any change a reboot is needed in order to see the effects.
Using these settings can also solve other performance issues after installing SP2 on WinXP.
