Subject: [dpdk-users] eal_memalloc_is_contig() is consuming a lot of cpu during initialization
Date: Fri, 03 Apr 2020 18:24:12 +0200 [thread overview]
Message-ID: <e881688317d1a85c3741d33bbbd61ddf@therouter.net> (raw)
Hi,
I am facing a strange behavior of my DPDK application on one particular
machine.
It takes about 30 seconds for the application to finish DPDK
initialization
procedures, while normally it takes less than 5-6 seconds.
During that time perf top shows that eal_memalloc_is_contig()
is consuming all cpu.
76.34% the_router [.] eal_memalloc_is_contig
DPDK version is stable-18.11.3 and
it's built for the westmere architecture.
cpu is Xeon(R) CPU X5650 @ 2.67GHz
How can I resolve that problem?
Thanks.
