    1. CO*Optimize the code first, then add compression.* - I beg to differ. Optimization is a time-consuming (=expensive) task which doesn't necessarily give desired results. Gzipping is a simple measure which only costs you about half an hour of configuring your server and then some CPU cycles for guaranteed results. Even for high-load sites, I'd say the reduced bandwidth is well worth any CPU cost (I/O is slower than CPU).

    2. CO@gustafc: Fair enough. But the thing to realize is that it's not free. And with modern Linux kernels and asynchronous I/O provided by most modern web servers is quite efficient (in terms of CPU cost for longer transfers). Sure, there will be some gain by adding compression, but it depends on your loading whether it's going to help (If you're CPU bound, it'll likely hurt you to compress. If you're disk or I/O bound, it'll help). It all depends what state your CPUs sit in most of the time...

    3. COI would suggest either using [mod_deflate](http://betterexplained.com/articles/how-to-optimize-your-site-with-gzip-compression/) (if you're using Apache) or PHP's built in [ZLib Output Compression](http://us.php.net/manual/en/zlib.configuration.php#ini.zlib.output-compression). They do a lot of checks for supported browsers, etc. There's no real need to do it in PHP if you don't have to (meaning if you can edit a `.htaccess` file, or `php.ini`)...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
