Old Intel E5300 2.6Ghz good enough for Mesa 7i76E?

Ok, so I bought the small PC.

After some intensive running of youtube, glxgears and some other random open windows, Test Results are as follows:

Servo thread max interval: 2164295, Max jitter: 1169015, last interval: 982595
base thread max interval 1215637, Max jitter 1190755, last interval 24917

I paid about $40 for it and can sell it to a family member if need be. Can also upgrade the RAM and CPU if it will fix it.

Note, I was using the internal WiFi card (some PCI type socket) as I could not get the normal Ethernet connected to the network for internet connection. This could probably also hinder the test.

So what is your verdict?

Now I tried the stretch image and the results are as follows:

Servo thread Max interval 1025346, Max jitter: 25829, Last interval: 998332
Base thread Max interval: 65721, Max jitter: 40721, Last interval: 24940

I tried doing everything I did in the previous test so hopefully it is comparable.

Latency test.
The photos in the following order.
Before loading the desktop; -After loading the desktop (a video on you tube and some pages opened randomly). -And the last 2 photos after closing what had opened.


What do you advise me, the pc is good or should I think of another?
I do not open music because I do not have sound on this pc. Video that I see on you-tube is only image, (without sound)
