[dpdk-users] Throughput dropping by half with 1B increase in packet size

2018-02-09 Thread Theano
Hi All, We are eventually going to build an application over DPDK, and we've started out with a very simple pktgen-like application that sends and receives packets to a different machine running l2fwd. With packets up to 64B (60B headers and payload + 4B of FCS), l2fwd shows line rate packet forw

If you have enabled them in $RTE_SDK/$RTE_TARGET/.config, they should be reflected in $RTE_SDK/$RTE_TARGET/include/rte_config.h. Do you see it defined there? If not, perhaps you forgot to run make, cd $RTE_SDK/$RTE_TARGET vi .config make The lib/librte_pipeline, librte_port should recompile and

Hi, I made sure that all the stats are enabled in the .config file. I did what you mentioned. Still, I stuck with the same problem(statistics isn't coming). Can you please let me know if I have to do some other steps to get my statistics in my ip pipeline application. Thanks, Sharanya On Thu, F

As you can see in the linker command --whole-archive was already used so link all dpdk libs: g++ -L/home/cuda1/git/dpdk-stable/x86_64-native-linuxapp-gcc/build/lib/librte_acl -L/home/cuda1/git/dpdk-stable/x86_64-native-linuxapp-gcc/build/lib/librte_mbuf -L/home/cuda1/git/dpdk-stable/x86_64-native-

You are probably missing another linker flag so - at a guess "--whole-archive". Please test with the testpmd app built using DPDK itself. /Bruce From: Victor Huertas [mailto:vhuer...@gmail.com] Sent: Friday, February 9, 2018 12:01 PM To: Richardson, Bruce Cc: users@dpdk.org Subject: Re: [dpdk-d

Nope, I use Eclipse CDT environment to compile (I add all the static libs manually and the executable is successfully generated). Regards, 2018-02-09 12:58 GMT+01:00 Richardson, Bruce : > Does it work with testpmd, built as part of DPDK? > > When you build the l3fwd-acl example do you use the DP

Does it work with testpmd, built as part of DPDK? When you build the l3fwd-acl example do you use the DPDK build system? From: Victor Huertas [mailto:vhuer...@gmail.com] Sent: Friday, February 9, 2018 11:54 AM To: Richardson, Bruce Cc: users@dpdk.org Subject: Re: [dpdk-dev] Nehalem Intel Xeon X55
