Subject: [dpdk-dev] [PATCH] Performance optimization of ACL build process
Date: Tue, 16 Aug 2016 17:01:27 +0300 [thread overview]
Message-ID: <20160816140128.10149-1-vladyslav.buslov@harmonicinc.com> (raw)
Hello,
In our application we need to be able to allocate tens of thousands of ACLs at runtime.
Testing revealed significant performance problems. We were able to track them to memset in calloc function which caused multiple page walks per invocation.
Modifying tb_mem to use huge page memory resulted ~2x performance gain for that operation.
Regards,
Vladyslav
