ADF Performance Improvement with Nginx Compression

We are using Nginx web server for Oracle ADF WorkBetter hosted demo hosted on DigitalOcean cloud server. Nginx helps to serve web application content fast and offer improved performance. One of the important tuning options - content compression, Nginx does this job well and is simple to setup.

Content compression doesn't provide direct runtime performance, a browser would run the same code, doesn't matter it was compressed or not. But it brings improved perceived performance (which is very important), network time is way faster, because of reduced content size. Oracle ADF is a server-side framework, each request would bring content from the server - faster this content comes, means better application performance.

1. Content Compression = OFF

Let see stats, when no content compression applied (using our Oracle ADF WorkBetter hosted demo).

Page load size is 2.69 MB transferred. Finish time 1.55 s:


Navigation to the employee section generates 165.76 KB and finish time 924 ms:


Navigation to employee compensation generates 46.19 KB and finish time 494 ms:


2. Nginx compression

Compression is simple to setup in Nginx. Gzip settings are set in nginx.conf, make sure to list all content types which must be supported for compression. Restart nginx process after new settings are saved in nginx.conf:


3. Content Compression = ON

Page load size is 733.84 KB transferred. Finish time 1.48 s:


Navigation to the employee section generates 72.75 KB and finish time 917 ms:


Navigation to employee compensation generates 7.59 KB and finish time 498 ms:

Hi Andrejus,
Has the application itself deployed into WLS?

ADF app must be deployed in WLS and Nginx is used as front HTTP proxy server.
