You can disable unneeded services, but to be honest, you're probably not going see a reduction in ping times.
Disable the following services...
-Alerter

-Error Reporting Service
-Help and Support
-Indexing Service
-Human Interface Device Access
-Machine Debug Manager
-Messenger
-Network DDR
-Network DDE DSDM
-Routing and Remote Access
-Secondary Logon
-SSDP Discovery Service
-Telnet
-Themes
-Wireless Zero Configurator (unless you use it for wifi)
