> New optimizations as now loaded on the production server so that you can

>
>         1. go to http://www.webpagetest.org
>         2. enter Website URL: http://www.aidaweb.si
>                 Test Location: Amsterdam
>                 Browser: Firefox
>                 Connection: FIOS (20/5 Mbps 4ms RTT)
>         3. Click START TEST
>
> With this setup I just got the following results:
>
>             Load Time  First Byte  Start Render  Requests  Bytes
>
>   First View  1.853s    0.199s        0.923s        43   440 KB
>   Repeat View 0.956s    0.125s        0.471s         3     7 KB
>
> So, only 200ms to the first byte and 1.8s for entire page of 43
> requests. This is twice as fast as before (unfortunately I lost results
> of previous tests). Also there are now all A and one X score:
>
>         A First Byte Time
>         A Keep-alive Enabled
>         A Compress Transfer
>         A Compress Images
>         A Cache static
>         X Content Delivery Network detected
>
> Another test is Google's PageSpeed from FireBug or Chrome (load
> PageSpeed addon first!),
>
>         Page Speed Score: 75/100 (up from 50/100 before)
>
> Here CSS sprites is what is still missing. CSS sprite are those small
> images on the page composed into only one image: so called CSS sprite.
> That way only one request is needed to load them all, instead of 20+
> now. I'm also working on this.
>
> Have anyone experiences with sprites ans specially using them from CSS?
>
> It would be nice if you test from other test locations too and post
> results here

>> Dear Aiders,
>>
>> While watching an excellent presentation by Ilya Grigorik from Google
>> Web Fast Team:
>>
>>       Faster Websites, Crash Course on Frontent Performance
>>       part1: http://parleys.com/#st=5&id=3648&sl=0
>>       part2: http://parleys.com/#st=5&id=3649&sl=1
>>
>> I come to idea to implement few optimizations Ilya mentioned in his talk:
>>
>> 1. web page is now streamed to the browser to start sending as soon as
>>    possible so that browser can start fetching CSS and JS files listed
>>    in page header in parallel. Until now a whole page was first
>>    rendered before start sending.
>> 2. gzip compression of page HTML and all other text resources like CSS
>>    and JavaScript. This reduces the load time substantially, usually
>>    about 5 times.
>>
>> End result is more than twice faster page load time, both time until
>> page starts rendering on browser and overall load time. We are now below
>> 250ms to the first byte time, which is nowadays a goal to regard your
>> site as a fast one. Note that this includes a DNS lookup time
>> (50-150ms), connection time (50-100ms) then content download.
>>
>> Another achievements are 4 A on http://www.webpagetest.org:
>>
>>       A First Byte Time
>>       A Keep-alive Enabled
>>       A Compress Transfer
>>       A Compress Images
>>       F Cache static
>>       X Content Delivery Network detected
>>
>> This F cache static is such because we instruct browsers to cache images
>> only 24 hours. For a reason to more easy upgrade web apps without
>> needing instruct the users to reload pages. They just wait one day...
>>
>> X Content Delivery Network, well, I'm not sure we would profit much to
>> use it except add another level of complexity ...
>>
>> Google regards such optimizations in this pageRank algorithm, which is
>> one of the reasons to be worthwhile.
>>
>> All those optimizations will be part of next Aida (and Swazoo) release,
>> it will also be soon on production server for http://www.aidaweb.si, so
>> that you can try by yourself :)
>>
>> Best regards
>> Janko
