Subject: [dpdk-dev] Why DPDK is not using compressed TRIE for LPM6 ?
Date: Thu, 25 May 2017 12:02:32 +0530	[thread overview]
Message-ID: <CAC4R1nnXGgG2HGA8xcnm7WTpTMva4Y87614HiBRbZNC6_Rq6Kw@mail.gmail.com> (raw)

Hello All,

I was doing some experiments related to LPM6 look up and I have added 20K
entries in the table. By looking at the rte_lpm6_lookup() code I found an
opportunity to compress the TRIE and there is a significant improvement
after compression.

Here are my questions:
Q1: Why DPDK is not doing the compression?
Q2. In the worst case the table will behave like an uncompressed TRIE and
in other cases, there is a scope of improvement. Is it worth doing?
