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:

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.
