Performance degradation after 2.7 version

[rainerborene]

There is something wrong with this image. I'm still investigating the performance issue.

First lets run a simple benchmark with the ruby:2.7 image:

root@localhost:~# docker run -it --rm ruby:2.7 ruby -ve 't = Time.now; i=0;while i<100_000_000;i+=1;end; puts "#{ Time.now - t } sec"'
ruby 2.7.5p203 (2021-11-24 revision f69aeb8314) [x86_64-linux]
2.271846678 sec

Then compare it with bitnami/ruby:2.7-debian-10 image:

root@localhost:~# docker run -it --rm bitnami/ruby:2.7-debian-10 ruby -ve 't = Time.now; i=0;while i<100_000_000;i+=1;end; puts "#{ Time.now - t } sec"'
ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-linux]
15.051291622 sec

I think this could be related to seccomp profile or misconfiguration of the base debian image. Please see these for more information:

• Default seccomp introduces significant overhead
• CPU-intensive Ruby/Python code runs slower on default-configured Docker
• support seccomp flags such as SECCOMP_FILTER_FLAG_SPEC_ALLOW (OCI Runtime Spec v1.0.2)

Hi,
I am opening an internal task to look into this.
At first sight, for the info in the links provided, it seems to be related to mitigations but also can be related to the compilation flags used when compiling ruby.
Have you checked if this only happens in the latest releases ?

We are going to transfer this issue to bitnami/containers

In order to unify the approaches followed in Bitnami containers and Bitnami charts, we are moving some issues in bitnami/bitnami-docker-<container> repositories to bitnami/containers.

Please follow bitnami/containers to keep you updated about the latest bitnami images.

More information here: https://blog.bitnami.com/2022/07/new-source-of-truth-bitnami-containers.html

Unfortunately and due to other priorities we didn't have the bandwidth to look deeper into this issue during this time and it is very likely that it will continue to be so in the near future.

This is still happening on the latest version:

docker run -it --rm ruby:3.1.3 ruby -ve 't = Time.now; i=0;while i<100_000_000;i+=1;end; puts "#{ Time.now - t } sec"'
ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [x86_64-linux]
1.686853438 sec

docker run -it --rm bitnami/ruby:3.1.3 ruby -ve 't = Time.now; i=0;while i<100_000_000;i+=1;end; puts "#{ Time.now - t } sec"'
ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [x86_64-linux]
15.878519018 sec

This is causing our CI to crawl to a halt when upgrading from 2.6. No issues with the generic ruby image.

No issues on the latest 2.6.10 image:

docker run -it --rm ruby:2.6.10 ruby -ve 't = Time.now; i=0;while i<100_000_000;i+=1;end; puts "#{ Time.now - t } sec"'
ruby 2.6.10p210 (2022-04-12 revision 67958) [x86_64-linux]
1.889140881 sec

docker run -it --rm bitnami/ruby:2.6.10 ruby -ve 't = Time.now; i=0;while i<100_000_000;i+=1;end; puts "#{ Time.now - t } sec"'
ruby 2.6.10p210 (2022-04-12 revision 67958) [x86_64-linux]

Hi,
I reproduced the issue with 3.1.3. I got better results than you, 1.4 sec for ruby and 7.1 secs for bitnami/ruby, but bad results in any case.
For 2.6.10 I got pretty similar results with ruby and bitnami/ruby, 1.4~1.6 secs.
I am bumping our internal task, but as @carrodher commented this could take a while.

We have no other choice than abandoning Bitnami images as base for our apps because of this issue.

Hi,
Finally we could tackle this issue, it is fixed in the latest releases.
Could you take a look to it ?
