Bcrypt for Node.js

Performance estimation between NAN and N-API implementation

Recently I worked on the porting of bcrypt for Node.js to the new N-API and
now I created this repository to do some experiments to estimate the performance
against the previous version impelented with NAN.

Environment

• Node.js Version 8.9.3

• OS macOS - High Sierra (10.13.2)

• MacBook Pro (13-inch, 2016, Four Thunderbolt 3 Ports)

• CPU 2,9 GHz Intel Core i5

• Memory 16 GB 2133 MHz LPDDR3

Experiments

I created two main experiments one where I used bcrypt to hash a password with
salt round parameter set to 10 and 11, and another where I used
bcrypt to compare password. Obviously I executed this for both synchronous and
asynchronous api that bcrypt expose. Eacher task was repeated 1000 times and than
I considered as result to compare the NAN and N-API version the avarage of the
time execution.

Results

Hash password using synchronous api and salt round set to 10

In average the N-API version of the addon is 1.74% faster than NAN version

Hash password using synchronous api and salt round set to 11

In average the N-API version of the addon is 1.82% faster than NAN version

Hash password using asynchronous api and salt round set to 10

In average the N-API version of the addon is 1.29% faster than NAN version

Hash password using asynchronous api and salt round set to 11

In average the N-API version of the addon is 0.74% faster than NAN version

Compare password using synchronous api and salt round set to 10

In average the N-API version of the addon is 4.19% faster than NAN version

Compare password using synchronous api and salt round set to 11

In average the N-API version of the addon is 2.97% faster than NAN version

Compare password using asynchronous api and salt round set to 10

In average the N-API version of the addon is 1.73% faster than NAN version

Compare password using asynchronous api and salt round set to 11

In average the N-API version of the addon is 1.33% faster than NAN version

Resources

You can find all raw data deriving from my work on the folder results

Web application

Added little and simple web application and test performance with autocannon
the reuslts are very similiar between the bcrypt implemented with N-API and NAN.
