Good evening, I wonder if anyone can help me with this.
I have over 1000 items in k2 divided into several categories, and since you get to climb about 200 articles began to take up the burden of k2 only when saving new article or new category, or to make changes to already created items or categories and also created delay and delay much, and sometimes get error 500.
The delay only occurs when saving.
Is it because the number of items k2 ?, who will?
I installed this extension:http://extensions.joomla.org/extensions/extension/extension-specific/k2-extensions/performance-booster-for-k2 but I see no improved K2 ...
Any suggestions, someone happened and could fix it?
Thanks in advance for your support.

PD: Please forgive my English, I am using google translator

Make sure that the VPS/ hosting enviroment you are using is not underpowered. A larger site's hosting requirements are different from a smaller (in content) site.

Finally be sure to ask your hosting provider about performance and how much memory is your site consuming.
