How to kill Sitecore whilst getting the languages for an item

I was reviewing a solution (not developed by Pentia) for a customer as they were concerned about the performance and stability of their site.

It didn’t take me long to find the following bit of code which calls the SQL server to find the languages for a given item:

languages

I was shocked that anyone would not use the Languages property on the Item class, which would have replaced the entire function.

I think in all my years of Sitecore development this is the worst bit of code I have ever seen, it shows  a complete lack of respect for the API and if  the site was upgraded it is possible that the database schema could change and therefore the code would break!

On average the SQL query took 400mS (which is quite slow, but then again the SQL server was getting hit by 4 front end servers for every request).

The same call to the Item.languages took 0.1mS, this simple change made every request 400mS quicker and reduced the load on the SQL server considerably.
