sysbench memory test - LMM - 04-27-2019
Hi,
I made some memory tests with rockpro64 and rock64. Here are the results :
The command is the following
Code:
taskset -c 0 sysbench --memory-oper=read --memory-block-size=1M --memory-total-size=20G --threads=1 memory runI used taskset to select a specific CPU
The command is ran 18 times and the rate is averaged.
Rockpro64 :
for CPU 4 and 5 : 5315 Mib/s
for CPU 0-3 : 1548 Mib/s
Rock64 :
for CPU 0-4 : 2114 MiB/s
What I found strange is that the results are rather better for rock64 f (A53 cores) eventhough rockpro64 RAM is LPDDR4.

I updated the kernel with the mainline kernel (5.0), and the performance seems really better for the rockpro64 :
- for CPU 0-3 : 2163 MiB/s
- for CPU 4 and 5 : 6760 MiB/s
Note that in this test, I used a block of 1M, this is rather big.
