Overview
RPO (Runtime Page Optimizer) is an IIS 6/7 webserver software component that increases performance of ASP.NET and SharePoint websites up to 200% or more.
The RPO works at runtime (no code changes required)
It applies three techniques:
- Compress + minify JavaScript and CSS files
- Combine multiple JavaScript, CSS and images into fewer files
- Caches optimized resources on the server and better client side caching - automatically caching images, JSS, CSS cached until they change on the server
Results: performance improvements by reducing the effect of latency from slow networks and long distance
Features
The RPO is an ASP.NET module, providing 9 optimization features in these three areas:
- Compression. Minifies and compresses JavaScript and CSS files. Optionally applies extra compression to JPGs
- Combination. Combines multiple JavaScript and CSS files into single files
- Creates CSS sprites of JPGs, GIFs and PNGs
- Caching. Client: Automatically sets and manages EVT tags and far future expiry dates for all resources. Server: caches optimized resources in memory or on disk
Optimization can be applies on a single page, selected pages, across an entire site or in "stealth mode" - so pages are optimized only for an administrator while evaluating and tuning the optimization.
