Subject: [dpdk-dev] perfomance of rte_lpm rule subsystem
Date: Tue, 19 Apr 2016 14:11:11 +0300 [thread overview]
Message-ID: <CAMKNYbzETqi3UJkdvMAcdoLVWx_3MQUiDxnmBrWT_49w5tXKRg@mail.gmail.com> (raw)
Hi.
Doing some test with rte_lpm (adding/deleting bgp full table rules) I
noticed that
rule subsystem is very slow even considering that probably it was never
designed for using
in a data forwarding plane. So I want to propose some changes to the "rule"
subsystem.
I reimplemented rule part ot the lib using rte_hash, and perfomance of
adding/deleted routes have increased dramatically.
If increasing speed of adding deleting routes makes sence for anybody else
I would like to discuss my patch.
The patch also include changes that make next_hop 64 bit, so please just
ignore them. The rule changes are in the following
functions only:
rte_lpm2_create
rule_find
rule_add
rule_delete
find_previous_rule
delete_depth_small
delete_depth_big
rte_lpm2_add
rte_lpm2_delete
rte_lpm2_is_rule_present
rte_lpm2_delete_all
P.S. the patch was made for 2.2.0 version.
P.P.S. Would it be more convinient to include full source file instead of
patch?
