For good real time
In general, notebook computers are optimized for size and battery life.
But Linux based CNC is running in Raspberry Pi and even smaller and lower
performance computers and dong fine.Performance is not needed. What is
needed is low latency real-time performance.

It depends what you want to test. I do a lot of my testing in VMs on
my Mac. That's perfectly OK for testing out
Checked once and concluded in general Laptops is a little bit more expensive
and have a little bit less perfomance in some combination. Internal expansion
ports are also limited.
This should come as no suprise unless ordinary computer is similar in size. In
general a smaller diameter 2.5 inch
My current laptop is an msi gs60 (4th gen i7. I have also had good
real-time performance from some lenovos. I would have to look at what I
have.

OK I'll have a try. Just out of curiosity. What is your laptop specs? I
have a friend who is a computer tech and I'm have gotten to about 9
computers from him at the moment. So we have some to play with.

It is the luck of the drawPCI will be issue. I use a laptop for
testing. I use mesa Ethernet cards and work great with my laptop..
Rt_preempt does seem to work well on laptops. From my experience - turn
off as much power saving as possible and turn off hyper threading.
Idle=poll in
Hey guys.
I saw that some guys are using laptops with linuxcnc. I only want them for
testing. Just wondering what laptops are good and any tricks to set it
up. I'm using Mesa pci cards so that might be a problem with a laptop.
But any ideas would be appreciated.
Regards.
Andrew
