Hi, sorry for the delay. The benchmarks took a while to get.
I got a bare metal test machine with Intel(R) Xeon(R) CPU E5-2660 v3 @
2.60GHz, running Ubuntu 18.04. Test kernels are compiled at
57a339117e52 ("selftests/seccomp: Compare bitmap vs filter overhead")
and 3650b228f83a ("Linux 5.10-rc1"), built with Ubuntu's
5.3.0-64-generic's config, then `make olddefconfig`. "Mitigations off"
indicate the kernel was booted with "nospectre_v2 nospectre_v1
no_stf_barrier tsx=off tsx_async_abort=off".
The benchmark was single-job make on x86_64 defconfig of 5.9.1, with
CPU affinity to set only processor #0. Raw results are appended below.
Each boot is tested by running the build directly and inside docker,
with and without seccomp. The commands used are attached below. Each
test is 4 trials, with the middle two (non-minimum, non-maximum) wall
clock time averaged. Results summary:
Mitigations On Mitigations Off
With Cache Without Cache With Cache Without Cache
Native 18:17.38 18:13.78 18:16.08 18:15.67
D. no seccomp 18:15.54 18:17.71 18:17.58 18:16.75
D. + seccomp 20:42.47 20:45.04 18:47.67 18:49.01
To be honest, I'm somewhat surprised that it didn't produce as much of
a dent in the seccomp overhead in this macro benchmark as I had
expected.
Below are commands used and outputs from time command.
Commands used to start the docker containers:
docker run -w /srv/yifeifz2/linux-buildtest \
--tmpfs /srv/yifeifz2/linux-buildtest:exec --rm -it ubuntu:18.04
docker run -w /srv/yifeifz2/linux-buildtest \
--tmpfs /srv/yifeifz2/linux-buildtest:exec --rm -it \
--security-opt seccomp=unconfined ubuntu:18.04
Commands used to install the toolchain inside docker:
apt -y update
apt -y dist-upgrade
apt -y install build-essential wget flex bison time libssl-dev bc libelf-dev
Commands to benchmark on native:
for i in {1..4}; do
mkdir -p /srv/yifeifz2/linux-buildtest
mount -t tmpfs tmpfs /srv/yifeifz2/linux-buildtest
pushd /srv/yifeifz2/linux-buildtest
wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.9.1.tar.xz
tar xf linux-5.9.1.tar.xz

make mrproper
make defconfig

umount /srv/yifeifz2/linux-buildtest
