IBM POWER9 Preliminary Benchmarks after CVE-2020–4788 mitigations

  • Kernel 5.9.9 from stable tree with mitigations=off kernel parameter.
  • Kernel 5.10-rc4 (commit 27bba9c5) from Linus tree with mitigations=off kernel parameter.
  • Kernel 5.10-rc4 (commit 27bba9c5) from Linus tree without the mitigations=off kernel parameter.

TLDR

Here’s a quick resume of the numbers I found. As can be seen, on CPU heavy workloads with little context switching, no significant difference has been found with the mitigations and between the tested Linux Kernel versions.

Bigger value is better.

Pgbench Benchmarks

Adding to previous tests below and by a suggestion from Karel Gardas, I've benchmarked the Kernel differences using Pgbench which is a bundled application from PostgreSQL to benchmark the database.

PostgreSQL 2 CPUs — Pgbench 2 threads

# Start PostgreSQL container with 2 CPUs
docker run --name postgres --cpus 2 -e POSTGRES_PASSWORD=mypass -d postgres
# Enter it's shell
docker exec -it -u postgres postgres bash
# Create test database
psql
CREATE DATABASE mydb;
exit
# Populate the database
pgbench -U postgres -i -s 50 mydb
# Run 10 test iterations with 60 clients and 2000 transactions each
for x in 1 2 3 4 5 6 7 8 9 10; do
echo "-------------- Run $x -------------- ";
pgbench -U postgres -c 60 -j 2 -t 2000 mydb;
done

PostgreSQL 6CPUs — Pgbench 4threads

# Start PostgreSQL container with 2 CPUs
docker run --name postgres --cpus 6-e POSTGRES_PASSWORD=mypass -d postgres
# Enter it's shell
docker exec -it -u postgres postgres bash
# Create test database
psql
CREATE DATABASE mydb;
exit
# Populate the database
pgbench -U postgres -i -s 50 mydb
# Run 10 test iterations with 60 clients and 2000 transactions each
for x in 1 2 3 4 5 6 7 8 9 10; do
echo "-------------- Run $x -------------- ";
pgbench -U postgres -c 60 -j 4 -t 2000 mydb;
done
