Frequently Asked Questions - 1

Adding DLE to the list of supported systems caused a stormy response (I noticed about 5 news on various pro-DLE sites ), so I will try to answer some of the most common questions below.

1. Web Optimizer paid project?
No, the project (at the moment) is absolutely free and downloadable. There are some plans for its monetization, but they have not yet been announced (maybe, only installation for sites with more than 1000 hits per day, for example, will be paid for). If you have any suggestions that would allow you to recoup quality development and would be beneficial to you personally, you can write them in the comments.

2. Web Optimizer from google?
No, the project is being developed by a group of activists (directly or indirectly related to webo.in ). Google Code is just hosting for files and SVN, almost narod.yandex.ru . You do not call sites on the People Yandex projects, right?

3. Web Optimizer loads the server?
No, the project is being developed to meet the highest performance requirements. On the contrary, if the server is properly configured, the load will only decrease. Let's consider such a case: on the page we have 3 style files and 5 script files. The average visitor views 3 pages at a time. Web Optimizer will create 1 script file and 1 style file. When loading each page, these files will only be checked for existence (this is less resource-intensive than their return to the user). Due to client caching, these files will be requested by the user only the first time they visit the site. Total we have a gain for each user in:
(3 + 5) * 3 - (2 + 2 * 3 * ~ 0,2) ~ = 20 requests to the server.
There is a clear advantage.

4. Bullshit full?
No, not complete :). The project is developed by domestic developers and in terms of functionality has no analogues in the world. With proper installation and configuration can accelerate the site about 10 times. Usually it is 3-5 times.

5. After installation possible errors?
Yes, of course. Since the application is non-commercial, not all cases are covered with tests. If you have any problems during or after installation, you should post them here.
http://code.google.com/p/web-optimizator/issues/list
they will be resolved fairly quickly (with an error reproduced by the description).

6. How many Google asked for a script?
While offers from Google did not arrive :)

7. Where and why does he climb?
The optimizer algorithm is rather complicated; in a nutshell it cannot be described. More or less detailed documents posted here (in English)
http://code.google.com/p/web-optimizator/wiki/Welcome
Briefly, Web Optimizer intercepts the output HTML from the server engine, optimizes it (creates cached versions of the required files) and sends to the browser already completely “overridden” (at the moment only the head section + is changed, if there are parallel hosts, the paths to them change in the document itself).

8. Many letters!
Here everything is described in much more detail:

if you wish, you can significantly increase your knowledge base on client optimization

9. Laziness to break the settings ...
The default settings are configured for optimal performance when installing the application. Web Optimizer itself is designed in such a way as not to overload with unnecessary information (there is a “Quick Install” mode). Also available options are "Change settings", "Update", "Clear cache" and "Delete."
