Here is a copy of the tool I wrote to test boards I use, your welcome to use however you like.
I have not experienced the issues others have probably because of how I do things verses how they may do things.

Actual set of REAL performance tests.

The tests are simple using stress-ng for 5 minutes and 10 minutes I warm the processor and heatsink up.
It then loads the processor with sysbench on 8 16 32 48 64 threads.
The test then measures the change in temperature of the processor during a 2 minute cool down.
Next it creates a ram disk as to not damage your emac or flash card.
It then launches in the ramdisk a script that generates 10,000 unique 2048 character hexadecimal palindromes. Then it changes the case of each abcdef to ABCDEF and writes to a second file. The second part of the script then takes one line at a time from the second file finds the match inn the first file and exits. Typically you will see LOAD numbers in the mid 60s. If the numbers do not match the test fails and it means there was data corruption. This same test run on and AMD Opteron 2.1Ghz 8 core Takes about 22 minutes typically.
After all the test are done it will create the report files and graph.
The script checks for the dependancies and installs them.
The test should only be used with proper power and cooling it will overheat the 1.50 cent solution posted recently.
Well, those benchmarks are not so REAL but rather lightweight and with a really cheap heatsink + fan ($1.50) performance results don’t look different at all. Here is my graph even if I don’t know what it should display other than temperatures all the time remaining below throttling treshold and therefore having no influence on performance anyway:
LOL! ‘And by showing that impressive amount of ignorance I totally reject reality’.
You’re a genius since you don’t get such simple facts that cpuburn-a7 is a heavy load and your scripted stuff only lightweight and laughable ‘load generation gone wrong’.
