Performance problems

["Boscovich, Maximiliano" <mboscovich@rectorado.unl.edu.ar>]

Hi People,

We are running FoxPro compiled application and it really slow on performance. 
We have 15 users running dosemu ( version 1.4.0+svn.1828-1 ) in the same server, 
with freedos ( "FreeCom version 0.84-pre2 XMS_Swap [Aug 28 2006 00:29:00]")    

and the statistics from sysstat are:

09:45:02          CPU     %user     %nice   %system   %iowait    %steal
 %idle
 09:55:06          all     28,68      0,00     71,32      0,00      0,00
 0,00
 10:05:02          all     28,81      0,00     71,19      0,00      0,00
 0,00
 10:15:20          all     26,96      0,00     73,03      0,00      0,00
 0,01
 10:25:02          all     26,42      0,00     73,24      0,00      0,00
 0,34
 10:35:03          all     26,59      0,00     71,90      0,00      0,00
 1,50

Always %system is more than 70% .

The server is a HP Proliat coreduo, and /proc/cpuinfo show this:

power management:

The Distro is Debian GNU/Linux, kernel :

Linux elmu 2.6.22-2-686 #1 SMP Fri Aug 31 00:24:01 UTC 2007 i686 GNU/Linux
	

The configuration is :

cat /etc/dosemu/dosemu.conf

$_cpu = "80686"
$_cpu_emu = "off"
$_rdtsc = (on)
$_mathco = (off)
$_hogthreshold = (1)
$_full_file_locks = (off)
$_xms = (16384)
$_ems = (0)
$_dpmi = (0x5000)
$_joy_device = ""
$_printer_timeout = (20)
$_speaker = "off"
$_sound = (off)
$_X_title = "Sipefco on GNU/Linux"
$_X_font = "-xos4-terminus-bold-r-normal-*-*-240-*-*-c-*-ibm-cp850"
$_X_mitshm = (off)
$_X_vgaemu_memsize = (512)

The users connects to the server with ssh -X.

Any idea how to improve the performance?. 

Well, Thanks and sorry for my english, i'm from Argentina.
