module: print amount of load time of a module #52213

H4ad · 2024-03-26T01:41:52Z

I was investigating why npm is slow and I started to figure out that was caused by it loading a lot of modules/js files, but I didn't know what are those modules or even how much time it took to load them.

So, this implementation came to my mind, and I used with the following commands:

NODE_DEBUG=module_cjs ~/Projects/opensource/node-copy-4/out/Release/node ./bin/npm-cli.js run echo --silent &> trace-node.txt

The log looks like this:

MODULE_CJS 413480 [/home/h4ad/Projects/opensource/performance-analysis/npm-cli/lib/commands/run-script.js] [../utils/did-you-mean.js]: 0.499ms MODULE_CJS 413480 [/home/h4ad/Projects/opensource/performance-analysis/npm-cli/lib/commands/run-script.js] [../utils/is-windows.js]: 0.102ms MODULE_CJS 413480 [/home/h4ad/Projects/opensource/performance-analysis/npm-cli/lib/base-command.js] [path]: 0.005ms MODULE_CJS 413480 [/home/h4ad/Projects/opensource/performance-analysis/npm-cli/lib/base-command.js] [@npmcli/config/lib/definitions]: 0.001ms MODULE_CJS 413480 [/home/h4ad/Projects/opensource/performance-analysis/npm-cli/lib/workspaces/get-workspaces.js] [path]: 0.003ms MODULE_CJS 413480 [/home/h4ad/Projects/opensource/performance-analysis/npm-cli/lib/workspaces/get-workspaces.js] [@npmcli/map-workspaces]: 0.051ms MODULE_CJS 413480 [/home/h4ad/Projects/opensource/performance-analysis/npm-cli/lib/workspaces/get-workspaces.js] [minimatch]: 0.055ms MODULE_CJS 413480 [/home/h4ad/Projects/opensource/performance-analysis/npm-cli/lib/workspaces/get-workspaces.js] [@npmcli/package-json]: 0.044ms MODULE_CJS 413480 [/home/h4ad/Projects/opensource/performance-analysis/npm-cli/lib/base-command.js] [./workspaces/get-workspaces.js]: 0.346ms MODULE_CJS 413480 [/home/h4ad/Projects/opensource/performance-analysis/npm-cli/lib/base-command.js] [./utils/cmd-list]: 0.027ms MODULE_CJS 413480 [/home/h4ad/Projects/opensource/performance-analysis/npm-cli/lib/base-command.js] [./utils/log-shim.js]: 0.012ms MODULE_CJS 413480 [/home/h4ad/Projects/opensource/performance-analysis/npm-cli/lib/commands/run-script.js] [../base-command.js]: 0.638ms MODULE_CJS 413480 [/home/h4ad/Projects/opensource/performance-analysis/npm-cli/lib/npm.js] [./commands/run-script.js]: 12.02ms

If we try to clean a little bit:

$ cat trace-node.txt | tr . , | sort -sbng -k5,16n -t ' ' | tr , . > formatted-timing.txt

The output was:

In this way, is very clear what is taking a lot of time to load npm, and I actually already opened a PR to fix one of the issues that appeared in this log (npm/cli#7314)

@joyeecheung suggest to include also the support for trace_events, so I created the debugWithTimer to introduce support for both ways extract information, via log or via trace:

$ ./out/Release/node --trace-event-categories node.module_timer --trace-event-file-pattern 'trace-events.log' ~/Projects/opensource/performance-analysis/npm-cli/bin/npm-cli.js run echo --silent

This will generate a trace-events.log file that can be imported on chrome://tracing or Perfetto UI to generate the following graph:

To be easier to read, I introduce two labels on the debugWithTimer, the first one will be for logging via NODE_DEBUG and the second one will be used at the trace.

GeoffreyBooth · 2024-03-26T05:09:05Z

Could this perhaps get its own label in NODE_DEBUG? I feel like optimizing module load time is an infrequent use case for debugging modules and these logging lines must be very spammy.

lib/internal/modules/cjs/loader.js

H4ad · 2024-03-26T14:06:32Z

@GeoffreyBooth I changed to TIMING_MODULE_CJS, we can also add support for esm under TEST_MODULE_ESM, and then we can measure both cases.

I didn't found any good alternative for this name, so I'm open to change this to another one if needed.

richardlau · 2024-03-26T14:37:36Z

Conceptually this feels more like something for trace_events than NODE_DEBUG?

H4ad · 2024-03-27T10:44:07Z

@richardlau Maybe I'm not familiar with trace_events but from what I see in the source code, I think it won't be as useful as having it as NODE_DEBUG since to be able to listen to the events we need to import trace_events and then createTracing.

The benefits of emitting these events through NODE_DEBUG is because it is very easy to listen to these events without any additional code, plus even importing trace_events will affect the events that will be emitted by this new debug, so I don't ' I don't think the implementation with trace_events will be as useful as this.

joyeecheung · 2024-03-27T13:13:29Z

createTracing() is for user-land tracing to get hooked into our tracing infra. Pretty sure internally we can just use internalBinding('trace_events').trace, which is already what we load during startup.

joyeecheung · 2024-03-27T13:15:45Z

Actually console.time() and console.timeEnd() is hooked into the tracing infra via internalBinding('trace_events').trace too. So for timing-related traces, adding some sort of support in debuglog to also emit traces via internalBinding('trace_events').trace sounds like a good idea. You get to both check out human-readable information via stdout, and get a trace file you can visualize using e.g. DevTools.

H4ad · 2024-03-28T02:45:36Z

@joyeecheung I changed the implementation to match what we discussed, I liked this new way, it will print in the stderr if the NODE_DEBUG=module_cjs or it will trace if the category is node. debuglog_{set}, in this case, node.debuglog_module_cjs.

I still have some tests to fix but in general the implementation is good enough to get some reviews.

H4ad · 2024-03-28T02:48:49Z

If we use the chrome://tracing, we can see what module is loading which module (I think we can improving this visualization).

H4ad · 2024-03-30T14:10:24Z

I fixed the tests and I also changed a little bit the visualization for trace, I updated the PR to include the new graph and the new logging example.

Tentatively backported in #56927 - backporting this reduces the conflicts, though it seems associated with some other later commits, some included regressions, so only tentatively backporting it together with the associated commits that I found, which seemed safe enough.
