Performance problems after changing the linux kernel from version 3.10.53 to 4.1.15

We are facing a general performance problem with kernel 4.1.15. In general the applications seem to be about 25% slower than under Kernel 3.10.53. We are using the same UBoot for both kernels with the same DDR-RAM configuration.

Has anyone had the same problem?

Any ideas?

Hi Oliver

please check as possible reason

Cortex-A9 ARM Errata 845369 

Also one can try with nxp official bsps from link below, they use kernel 3.10.53 with

uboot v2014.04 and kernel 4.1.15 with uboot v2015.04
