Hello all, When upgrading meta-linaro/meta-linaro-toolchain from daisy to fido, we faced drastic performance downgrade (-34.06%) on linux ipv4 forwarding. The board is ls1021atwr (ARM Cortex-A7 MPCore compliant with ARMv7-A architecture).
We did some investigation, and suspected that it is caused by the toolchain upgrade. Did someone meet similar issue? The detailed toolchain info: https://git.linaro.org/openembedded/meta-linaro.git/shortlog/refs/heads/fido gcc-linaro-4.9.3-2015.03, glibc-linaro-2.20-2014.11, binutils-linaro-2.25-2015.01 https://git.linaro.org/openembedded/meta-linaro.git/shortlog/refs/heads/daisy gcc-linaro-4.8.3-2014.04, eglibc-linaro-2.19-r2014.04, binutils-linaro-2.24-r2014.03 thanks. -Ting
