This is almost a similar response as your other thread but most of these are very simple queries which doesn't do a "scan" on the entire table because of the indexes. It's perfectly fine unless you are having issues with the load.

I often have overloaded server. Statistics also very often overload, over 6 or more

Hello Andregh,

If your server is overloaded, you need to ask your hosting provider for "slow logs". By the way, there's a known performance issue on EasySocial 1.2.7 but will be resolved in 1.2.8
