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!
