Re: [dpdk-users] Too much time in mmap()
I am using 16.07. Is it already 'too old'? -_-;;; Almost time is spent on mmap() not the memset() 2017년 1월 4일 (수) 오후 6:16, Thomas Monjalon 님이 작성: 2017-01-04 08:08, Chae-yong Chong: > Hi, > > Too much time is spent on mmap() in rte_eal_init(). > When running DPDK application with 35 1G huge pages, it takes about 12sec > in mapping(). > Is there any way to reduce this time? I guess you are using an old DPDK. You just need to upgrade :)

Re: [dpdk-users] Too much time in mmap()
Which DPDK version are you using? In DPDK16.04, below url did some optimization work. http://dpdk.org/ml/archives/dev/2015-November/028598.html -Original Message- From: users [mailto:users-boun...@dpdk.org] On Behalf Of Chae-yong Chong Sent: Wednesday, January 04, 2017 7:08 AM To: users@dpdk.org Subject: [dpdk-users] Too much time in mmap() Hi, Too much time is spent on mmap() in rte_eal_init(). When running DPDK application with 35 1G huge pages, it takes about 12sec in mapping(). Is there any way to reduce this time? I guess it is okay to have that much time in first initialization. However, if the application is restarted for some reason(for example, unexpected exit) that long initialization can cause service continuity. May the Fun with you.
[dpdk-users] Too much time in mmap()
Hi, Too much time is spent on mmap() in rte_eal_init(). When running DPDK application with 35 1G huge pages, it takes about 12sec in mapping(). Is there any way to reduce this time? I guess it is okay to have that much time in first initialization. However, if the application is restarted for some reason(for example, unexpected exit) that long initialization can cause service continuity. May the Fun with you.
