I am way out of my depth but have got confused. I am running test at moment and these are the results I am getting
Max Interval & Max Jitter
Servo 1ms , -- 10,571,476 , & 9,571,476
Base 25 , --- 30,648,909 , & 30,623,909
Do these make sense?

Edit
Having now read the topic on latency it would appear this machine is not suitable? When I first ran the test it was about 20,000 and I thought ok as it compared with the list of machines that are ok. Having set up the Ethernet to be onboard could that have upset the apple cart?

More info required. What model and type of PC/laptop is this?

What do you mean by "Having set up the Ethernet to be onboard"? Please elaborate.

Edited, thank you for pointing that out.

Sorry for being vague HP 500 B MT desktop.

The motherboard has an onboard ethernet built in and in addition there was an ethernet card to which the internet was connected in the only slot available for a parallel port card.

The main problem I have found with big name business PC has been the poor BIOS installed. They trim features out such as the ability to turn off power management, virtualization and speed steeping for less problems with tech support.

For best latency test results I always recommend a motherboard with a full featured BIOS. The gaming versions usually have all the features left in the menus for BIOS tweaking.
