Well, when you say (as you did in your first post) "Since last week our server become too slow" that is a pretty good clue. Pay attention when the users of a system say that they notice a difference.

Load average is the average number of processes that want a cpu (or will want want a cpu very soon) but cannot get one. But it also includes currently running processes (since they too must want a cpu). It is not a percentage. 20 is generally very high but with enough cpu's it might be ok. If you had 32 cpus, some of them would be idle and you would have no problem at all.

The percentages are indicated by this symbol % (which we call a per cent sign). Look at your idle percentage. It is zero. That means you are maxed out. Adding cpu's would probably help.
