The problem is, that no tool shows the real CPU
Usage. Top shows the top 20 processes. But together
they cost about 5 % CPU Usage. If I sum all
processes, I get about 10%. Who uses the
rest?

prstat and other tools show the same.
Have you checked the process table? Perhaps you have many small processes caused by an endless loop like:

A user has /bin/sh as a login shell and wants start another after login and writes in his .profile the following line which can cause such as situation:
/bin/zsh --login

Check for similar things and small problems on your systemSmilie

Exacct::Object::Item(3PERL)				      Perl Library Functions				       Exacct::Object::Item(3PERL)

NAME
Exacct::Object::Item - exacct item manipulation SYNOPSIS
use Sun::Solaris::Exacct::Object; my $ea_item = Sun::Solaris::Exacct::Object::Item->new( &EXT_UINT64 | &EXC_DEFAULT | &EXD_PROC_PID, $$); DESCRIPTION
This module is used for manipulating libexacct(3LIB) data Items. A libexacct Item is represented as an opaque reference blessed into the Sun::Solaris::Exacct::Object::Item class, which is a subclass of the Sun::Solaris::Exacct::Object class. The underlying libexacct data types are mapped onto Perl types as follows: libexacct type Perl internal type EXT_UINT8 IV (integer) EXT_UINT16 IV (integer) EXT_UINT32 IV (integer) EXT_UINT64 IV (integer) EXT_DOUBLE NV (double) EXT_STRING PV (string) EXT_RAW PV (string) EXT_EXACCT_OBJECT Sun::Solaris::Exacct::Object subclass Constants None. Functions None. Class methods Class methods include those inherited from the Sun::Solaris::Exacct::Object base class, plus the following: new($catalog, $value) This method creates and returns a new Sun::Solaris::Exacct::Object::Item. The catalog tag can be either an integer or a Sun::Solaris::Exacct::Catalog. This catalog tag controls the conversion of the Perl value to the corresponding Perl exacct data type as described in the table above. If the catalog tag has a type field of EXT_EXACCT_OBJECT, the value must be a reference to either an Item or a Group object and the passed object is recursively copied and stored inside the new Item. Because the returned Item is constant, it is impossible, for example, to create an Item representing CPU seconds and subsequently modify its value or change its catalog value. This behavior is intended to prevent mismatches between the catalog tag and the data value. Object methods Object methods are those inherited from the Sun::Solaris::Exacct::Object. Exports None.
