QUESTION
I am trying to benchmark an Object's member function using Benchmark.js. Testing the function is made difficult by several factors:
- Creation of the object is asynchronous (I could mock that part)
- The member function is expensive
- The member function is smart enough to only run once
Let's say it looks like this:
...ANSWER
Answered 2020-Feb-03 at 22:00I'm not going to accept this answer, because I don't have enough knowledge on the subject to be 100% positive, but I did want to share what I found. If this should be moved to my question or a comment, just ping me with a comment.
I think the reason this isn't possible is because of how Benchmark.js performs its timing.
From what I've read (both in text and in its code), Benchmark doesn't time and sum-up individual runs, but instead counts how many runs complete over a specified amount of time (default = 5 seconds). This avoids certain gotchas like low-precision timers/timestamps, run-time optimization, and floating point rounding errors.
So it can't simply subtract the time it takes to execute the per-run setup function, due to those reasons. It also can't pause its timer to allow the per-run setup to execute.
For these reasons, it seems that Benchmark.js does not support per-run setup functions, because doing so would throw too much of a wrench in its works and reduce the timing accuracy.

I'm trying to write a script that can add the package.json dependencies from one project to another one programmatically.
This is probably trivial jq, although I did search around and couldn't find anything that does this exactly.

QUESTION
I'm trying to find a better way to run some cpu bound tasks using NodeJS. There are 2 options as I know, fork processes and worker threads. So I have ran a benchmark between them and found out that fork process is faster.
So, I have some questions here:
- Why is the fork process method faster?
- Are the worker threads useless? Or what are the worker threads advantages, consumes less cpu/memory?
I'm running the code on MacOS(2.2 GHz Intel Core i7, 16 GB 1600 MHz DDR3) using node v10.15.3
the benchmark code is in my gist:
threads pool library microjob and process pool library node-worker-farm are used in my code as you can see. The running cmd is : node --experimental-worker benchmark.js
ANSWER
Answered 2019-Jul-08 at 07:22I think @gireeshpunathil's comment from https://github.com/nodejs/help/issues/1920 can help a lot:
there is no single formulae that computes which method will be faster. It depends on a number of parameters:
- the running time of the job itself
- the interaction of the job with the spawning code
- the machine characteristics, specifically cpu, memory and scheduling
the fork uses native fork and exec, that is heavy-weight than thread creation. fork creates a new node instance with new v8, isolate, libuv etc. worker does not create new node instance. forked process uses IPC channel to talk to the forking process, if needed. workers use in-memory buffers.
So:
- if the execution time of the microjob is too small compared to the process creation, worker method will be faster.
- if the job communicates with the driver, the frequency of communication and the cost of communication will decide the winner
- if the job runs as long independent piece of code with no interaction, fork method will eventually prove faster (I think that
is happening here)

QUESTION
I was doing the benchmarking of MongoDB 3.2.17 for fun and cannot understand the reason for this behavior.
When I create an empty collection prior to doing insertion
MongoDB x 906 ops/sec ±2.78% (75 runs sampled)
When I don't create any empty collection and just simply run
insertManyMongoDB x 87.81 ops/sec ±94.31% (71 runs sampled) // Error Rate is high, why?
My Code that uses Benchmark.js so that you can point if I made some mistake there
...ANSWER
Answered 2018-Mar-08 at 19:56This is quite simple. You are inserting the same 100 records in every run.
When you drop the collection between every run, you are measuring how long it takes to drop collection and then insert 100 documents into it.
When you comment out dropping the collection, you insert the 100 records in the first run, but then your subsequent runs are each attempting to insert the exact same 100 documents into the same collection and they are all getting the error:
QUESTION
Hello guys I'm trying to learn Webpack I've been following some tutorials and I've run into some problems. I've installed webpack locally in folder I am working in with npm install webpack --save-dev. I made two JS scripts and I wanted to bundle them and I've tried following command webpack script-1.js /.bundle.js in WindowsPowerShell (I'm using Windows 7). Now this made the following error
webpack is not recognized as an internal or external command operable program or batch file
So then I installed webpack globally, and when I used the same command in PowerShell (I have opened it as an admin), it made bundle.js file but not in the directory I was working in, but in C:
Now after this failure I've decided to try using git bash. First I've tried this command webpack script-1.js /.bundle.js and got the following error
bash: webpack: command not found
Finally after some trying I was able to make it work using this command in git bash node_modules/.bin/webpack ./script-1.js bundle.js
Is there a way to fix this, so I can just type webpack instead of whole path ? Also is there a way to fix path in PowerShell ?
This is mine package.json
...ANSWER
Answered 2017-Apr-06 at 04:48That kind of path is what is used in a git for Windows bash.
See this issue
We use cmdr (http://cmder.net/ ) to emulate console on Windows machines.
Still we had to modify scripts and separate build to clean and build tasks to get it working.
QUESTION
I am evaluating how WebCrypto performance compares to third-party crypto libraries SJCL and Forge. I would expect WebCrypto to be much faster since it is a native browser implementation. This has also been benchmarked before and has shown such.
I have implemented the following tests using Benchmark.js to test key derivation (PBKDF2-SHA256), encrypt (AES-CBC), and decrypt (AES-CBC). These tests show web crypto to be significantly slower than both SJCL and Forge for encrypt/decrypt.

...ANSWER
Answered 2017-Mar-13 at 20:46I have a hunch that, with such a short message length, you're mostly measuring invocation overhead. With its asynchronous promise-based interface, WebCrypto probably loses out a bit there.
I modified your encryption benchmark to use a 1.5 kib plaintext, and the results look very different:
