I installed Mach and the xml from the vendor and was up and running in less than an hour
If your hardware matches one of the included configurations should not even take that long to get going with LinuxCNC now that you have some experience.
If you need to create a new configuration and you know your settings from Mach, such as parallel port pin numbers, driver information, speed, acceleration, machine size, etc. run Stepconf and you can be up and running in no time.
Be sure to read the getting started section.

Latency Test:
(I have 3 identical machines currently running onobard LPT and onboard video, but I could change those if need be.) I have some new LPT cards laying around.

I test one so far. I would expect the other two to react similarly:

Servo Thread
Max Interval 1003848
Max Jitter 7812
I did show a higher (about 25000 at one point, but I was unable to repeat it when I restarted the latency test.) I may have also read the wrong thing as I was hoping tons of windows and moving things around to try and ge the worst possible numbers.)


Base Thread
Max Interval 46006
Max Jitter 21413

Just checked. It was not set to EPP mode in the BIOS. (That machine was not connected to a G540. Its just the only one I had that wasn't running a job at the moment.)

Will retest...

As soon as a opened a couple windows it shows 25K max jitter on the servo thread. Other numbers were similar.

Not brilliant, but perfectly acceptable.
