Performance and Scalability

Drupal Computing is a framework that facilitates distributed computing between Drupal and external programs written in non-PHP languages such as Java and Python. It is particularly designed for the cases where you need to use Drupal with non-PHP, computational-intensive code libraries (such as Apache Mahout, NumPy/SciPy, R, etc) for offline big data analytics.

This adds a new plugin for Views Content Cache to support taxonomy terms by ID via Views arguments.

This has been created as a sandbox, because this module is based on Views 3, which is not supported by Views Content Cache for Drupal 6.

Adds 2 custom delegates to the http_client module:

1. Core delegate, uses drupal_http_request instead of curl_exec to run requests
2. Http Parallel Request delegate, uses httprl module to run requests

Jumpple Drupal module Monitor Your Business For Uptime And Performance
If you’re waiting for customers to bring website problems to your attention, you’re waiting too long. For every customer who calls and complains about site downtime, shopping cart issues, or slow load times, there are a dozen more who do not report performance issues they experience.
If your Drupal website or any of its features are down, that means you’re losing business. You need to take proactive steps to keep on top of your website 24 hours a day, whether you’re working or not.

This is a small helper module which will automatically lazyload all images for sites with multiple images, which will make the site load faster.

All images will only load when it's visible to the browser window.

Available Settings:
1) Enable/Disable
2) Distance - image distance from the viewable browser window before the actual image loads
3) Placeholder Image - stand-in image
4) Loader Icon - animating icon (shamelessly borrowed from ajaxblocks module)
5) Excluded Pages - page paths to be excluded from image lazyload

The Alternative Database Cache module is a drop-in replacement for Drupal Core's default cache implementation. Its goal is to fix long-standing problems with Drupal's core caching mechanism.

This is a small helper module which will automatically lazyload all blocks for sites with multiple blocks, which will make the site load faster.

This is a small helper module which will automatically lazyload all nodes for sites with multiple nodes on a page, which will make the site load faster.

All nodes will only load when it's visible to the browser window. Similar to Block Lazyloader but this time it's the node content.

3th party widgets can cause a huge performance hit. In order to improve the performance, some sites - like Mashable - will load the widget on mouseover. A 'dummy' widget is included in the page HTML, with the counts loaded on the server via a 3th party API. The lazyloaded module brings this functionality to Drupal.

Currently supported widgets are Twitter tweet, Facebook like and Google +1. This module is a work in progress and we are working to make the whole system more flexible.

An easy to use simple helper module for making your images responsive.

Features:

1. Loads the correct image size depending on the set image breakpoints, this means that you have to set image styles for these breakpoints.
2. Only loads when it shows on the browser window
3. Responsive images do not directly depend on the window's width but on the image container which can have % width of the window.
