Samba on E3500 Poor Performance!!!

Hi you all, I have a BIG performance problem on an Sun E3500, the scenario is described below:

I have several users (30) accessing via samba to the E3500 using an application built on Visual Foxpro from their Windows PC , the problem is that the first guy that logs in demands 30% of the E3500 CPU, the second one demands 3.2 % and so on until the CPU gives 0.0% of attention to the last 25 users, so I received claims all day long, my questions is:

How can I order to samba not to spend a lot CPU in a single task?, or Is it a Visual Foxpro code problem? or Can I change the priority of the samba processes? How? Can it be fixed with a Patch?

Im runing on a Solaris 2.6

Please help.

NAME
pmdasamba - Samba performance metrics domain agent (PMDA) DESCRIPTION
pmdasamba is a Performance Metrics Domain Agent (PMDA) which exports metric values from Samba, a Windows SMB/CIFS server for UNIX. In order for values to be made available by this PMDA, Samba must have been built with profiling support (WITH_PROFILE in "smbd -b" output). This PMDA dynamically enumerates much of its metric hierarchy, based on the contents of "smbstatus --profile". When the agent is installed (see below), the Install script will attempt to enable Samba statistics gathering, using "smbcontrol --profile". INSTALLATION
If you want access to the names and values for the samba performance metrics, do the following as root: # cd $PCP_PMDAS_DIR/samba # ./Install If you want to undo the installation, do the following as root: # cd $PCP_PMDAS_DIR/samba # ./Remove pmdasamba is launched by pmcd(1) and should never be executed directly. The Install and Remove scripts notify pmcd(1) when the agent is installed or removed. FILES
$PCP_PMDAS_DIR/samba/Install installation script for the pmdasamba agent $PCP_PMDAS_DIR/samba/Remove undo installation script for the pmdasamba agent $PCP_LOG_DIR/pmcd/samba.log default log file for error messages from pmdasamba SEE ALSO
pmcd(1), smbd(1) and samba(7). 3.8.10 Performance Co-Pilot PMDASAMBA(1)
