Subject: [dpdk-dev] Why DPDK is not using compressed TRIE for LPM6?
Date: Sat, 27 May 2017 00:34:57 +0530	[thread overview]
Message-ID: <bc76760208b5b2c851e23b116d0a1384@cse.iitd.ac.in> (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?

Thank you!

Atul Shree
