feat(perf): add nim-libp2p v1.1 by lchenut · Pull Request #262 · libp2p/test-plans

lchenut · 2023-08-16T10:15:12Z

I'm a bit rusty with docker though, so I'm not 100% sure if what I did is correct.

@lchenut missing step (2) and (3).

For a new implementation, in impl/Makefile include your implementation in the all target.

For a new version, reference version in runner/src/versions.ts.

Excited to see the results.

perf/impl/nim-libp2p/v1.0/Makefile

+perf: perf.nim nim-libp2p
+	docker run --rm --user "$(shell id -u):$(shell id -g)" -v "$(shell pwd)":/usr/src/myapp -w /usr/src/myapp nimlang/nim:1.6.10 sh -c "cd nim-libp2p && nimble install_pinned && cd - && nim c --NimblePath:nim-libp2p/nimbledeps/pkgs -p:nim-libp2p -d:chronicles_log_level=WARN --threads:off -d:release perf.nim"


CI has failed:

bash: line 1: ./impl/nim-libp2p/v1.0/perf: No such file or directory

Is this actually producing a binary under the name perf?

That's what I was afraid of. It's a Docker problem, it creates an ELF executable, no matter what, where it should create a host-compatible executable.

But it seems that there's no nim image on docker hub with this option.

After a bit of research, the problem doesn't come from the executable itself, but come from the linking of the .so...

$ file perf perf: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=895de8bd9fdf766ac9448fa05056cb4370bb6f54, for GNU/Linux 3.2.0, not stripped

/lib64/ld-linux-x86-64.so.2 isn't found

And I have no idea what I should use instead.

mxinden · 2023-08-31T15:57:23Z

Friendly ping @lchenut. Any progress on the above linking issue?

lchenut · 2023-09-05T13:07:35Z

Hum... I was so sure about this one. After a bit of digging and not finding a clear way to fix this (non-existant). It seems that I forgot to include nim-libp2p/v1.0/. in a .PHONY. So nothing to do with linking.

mxinden · 2023-09-06T15:05:02Z

Cool. Mind resolving the merge conflicts @lchenut? I can then trigger another run.

@mxinden done

Menduist · 2023-09-14T15:30:00Z

@mxinden friendly ping to trigger the CI :)

Sorry for the delay. I was out sick with COVID for a week. Resolved conflicts with #299 and triggered CI:

Hi @mxinden, we often find ourselves needing CI runs for our PRs but lack the necessary permissions. Is there a way to streamline this process to minimize manual coordination? Thanks.

mxinden · 2023-10-26T12:32:23Z

Is there a way to streamline this process to minimize manual coordination? Thanks.

In case you want to run the perf tests off of your laptop against your own AWS account:

https://github.com/libp2p/test-plans/blob/master/perf/README.md#running-manually

In case you want to run the perf tests off of the nim-libp2p CI, you would need to run against your own AWS account. For that, the ./terraform/modules/long_lived module provides additional tooling, namely an AWS lambda that cleans up left over resources, just in case. Once that is in place, you can trigger the perf workflow off of the nim-libp2p CI with your AWS credentials.

Either way, I can't give you access to the Protocol Labs AWS account.

@mxinden It's my bad, I should have pinged you when I pushed last week. Like the last three times, it should work now.

mxinden

I am sorry that this is dragging along.

Unfortunately the output format has changed in the meantime. I don't expect this requires a large change on your end, though you will need to continuously emit the current throughput every 1s.

You can find the larger rational in #261. I expect this to be especially interesting for you, given that you looked into congestion controller slow start for your upcoming Gossipsub optimizations.

mxinden · 2023-11-20T19:09:18Z

perf/impl/nim-libp2p/v1.1/perf.nim

+  dur = dur + (await PerfClient.perf(conn, f.uploadBytes, f.downloadBytes))
+  let ns = dur.nanos
+  let s = Second.nanos
+  echo "{\"latency\": ", fmt"{ns div s}.{ns mod s:09}", "}"


Note that the output format has changed with #276.

The pull request updated the documentation. You can find the new output format here:
