The performance difference correlates with the number of inline functions. Petri is currently working on a patch set, which inlines a large set of commonly used packet functions. It’s probably best to wait until his patch set is ready (probably tomorrow?) before running the tests. -Matias

For your benchmarking it would be good to get a comparison run without those options to better quantify the overhead of ABI compatibility mode. Right now we're taking a strict approach to ABI so as to minimize the coordination requirements between implementations supporting that ABI, however it's possible to tighten things up by allowing certain inline function expansions if the members of the ABI agree on some common aspects of their respective internals.

Thanks, with this configuration it is working.
My doubt here is:
Why we are not using shared lib, and abi-compat ??

Hi Gyanesh,
Odp-linux currently supports DPDK v16.07. With these steps everything is
working for me:
# DPDK install
cd
git checkout v16.07
make config T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc
cd x86_64-native-linuxapp-gcc/
sed -ri 's,(CONFIG_RTE_LIBRTE_PMD_PCAP=).*,\1y,' .config
cd ..
make install T=x86_64-native-linuxapp-gcc DESTDIR=./install EXTRA_CFLAGS="-fPIC"
# odp-linux install
cd
./bootstrap
./configure --with-dpdk-path=
/x86_64-native-linuxapp-gcc --disable-shared -disable-abi-compat
make
Were you doing something differently?
Regards,
Matias
