NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Simple Script of Resumable Upload with Google Drive API for Node.js

This is a simple sample script for achieving the resumable upload to Google Drive using Node.js. In order to achieve the resumable upload, at first, it is required to retrieve the location, which is the endpoint of upload. The location is included in the response headers. After the location was retrieved, the file can be uploaded to the location URL.

In this sample, a PNG file is uploaded with the resumable upload using a single chunk.
