Dosemu Slower than CMD

Dosemu Slower than CMD

[Eddy Setyawan]

Hello DosEmu Mailing list,

I am new here... i have a problem i hope guys here can assist me solve it

i try to run application made using clipper when run in w*nd*ws cmd
command, and do some process it is a little bit slower user can feel
it have a delay but not more that 1 secs, but when i run it in dosemu,
it take more than 5 secs i don't know where this problem cause,
because the application is made by other person
any suggestion? or perhaps do i need to attach the application so you
guys can try on ?

thanks

NB:
w*nd*ws is run on Pentium 3 733 machine
dosemu (v. 1.4.0) is run on Linux Fedora 8 on AMD 64 3000+ machine

regards,
Eddy Setyawan

You probably run a 64-bit linux. In 64-bit mode, the processor can't run 
realmode or
16-bit dpmi applications, so dosemu has to emulate the binary programcode.
If you have got an diskimage with an window on it, you could run that 
image in kvm.
On my machine, clipper code with many accesses to disk is much faster 
when run with kvm
than in dosemu.
The other option would by to run a 32-bit linux, perhaps from a life cd.

Dear All,

Hello Mr. Bambang, your guess I am from Indonesia is correct :)
perhaps you recognized from my email address or my bad english :p
anyway i can't change for hogthreshold option, it will eat more cpu
resource and i will run more than one session dos in one computer, so
i think it will eat all CPU

Hello Mr. Reinhard, My machine is 64bit but i'm run Fedora 8 using 386
arch. I can't use KVM either i need to run clipper app in many session
not only one so sharing disk is imposible except using network drive.

I found information about samba mounting in dosemu is this can
increase disk access performance?

It depends on what you are using now for file sharing. If you use e.g. 
mars_nwe or netware, then yes it can. Remember that "samba for dosemu" wasn't 
tested on 64bit distributions yet. I successfully run it on 32 bit 
distribution with hogthreshold = 1. Of course if your application needs more 
cpu power eg. for counting sth, hogthreshold = 1 could be not enough.

Anyway... you should consider switching to 32 bit distribution if you are 
aware of emulation accuracy and speed.

- When is section of Your program slow, it does any CPU-intensive task,
   or rather I/O intensive?
- Your DOS files are on native DOS partition, or on Linux filesystem?
- application is slow always, or only sometimes?
- Is slow only when there runs multiple those clipper apps, or is
   slow when run only one too?
- You run DOSEMU under console or X Window?
- Did You run any diagnostic tools, e.g. "top", "sar",...?

Re: Dosemu Slower than CMD

[Eddy Setyawan]

Dear All,
Hello Frantisek,  my program going to slow when clipper application
entering section reading a lot of data in database, CPU is going up
eating all available resource, but I/O activity i don't know how to
check it ?
I am using Linux filesystem using lredir command.
When doing reading or writing simple database it run fast, as fast as
CMD do, also i try to run it several instance it still acceptable
fast, not for high load process, i just run it to test only one
instance but it slow. example when run it in CMD it takes 1-3 secs but
using dosemu it takes 10-15secs
Application is run under console mode
diagnostic using top application show high activity on system CPU

I've upload the application if some one can help me to see it what is wrong?
links is here : http://www.megaupload.com/?d=NDQXRF1X

please edit config.sys first set files = 200 and buffer = 100
to run application enter folder MITRA\PRG run SL.EXE
when run login information is Name = A, password = 1234
the process I mean is at menu Master -> Persediaan -> Ubah Harga Jual,
wait until data is show it will take to long than usual.

anyway thanks for all support this mailing list

Eddy Setyawan

Dear All,
Sorry, I'm sure many of us not using IE for browser, in case
megaupload using firefox need an add ons, I'm also upload at different
server

You might try top. Also, you might try the system monitor. I use
FC2, and have one under Red Hat-> System Tools -> System Monitor
using Gnome.

it run CPU to 100% task, i've ask the programmer who code it, and he
say that process is do so many task but in CMD it run fast even i look
at task manager CPU usage jump to 100% but only less than 1sec using
dosemu it takes more than 10secs

it is Linux filesystem... i need run on it for sharing each user run it

only sometimes

I try run only 1 apps it run slow

run in console bcause my plan is run it remotely with ssh

i don't know what is sar, but using "top" show that dosemu process eat
CPU to 100%

Re: Dosemu Slower than CMD

[Frantisek Hanzlik]

Hello,
I download Your app (mitra.tar.bz2: sl.exe etc) and configure and run it
as You reccomended in mail from 16-Mar-2008, with config.sys param
"buffers=10" (leaved at dosemu default value - as I/O is cached at Linux
side, I not see any benefit from increasing number of buffers.
And available DOS memory was 630kB for "buffers=1", and only 578 kB for
"buffers=100". Difference in app speed wasn't perceivable.

At PC with 5 years old P4 2.4GHz (Northwood) CPU/1GB RAM/320GB SATA HDD
  and dosemu 1.4.0-svn_1844 it take about 6 sec.
At PC with E8200 Core2 Duo 2.66 GHz (Wolfdale) CPU/8GB RAM/750GB SATA HDD
  and dosemu 1.4.0.1-4.svn1858 it take about 3 sec.
On both PCs run Fedora 9.

Then I run it with some dosemu debug options (+9#DTEMx - note: this
produce ~ 200MB log file and dosemu must be patched for it, as it log
circular log with limited size - see "src/include/dosemu_debug.h" and
"src/base/misc/utilities.c").
After some logfile analysis I got these results about called functions:

  70707 : int2f_1108-network_read-from-file

Maybe this program section is slow because it has many read attempts,
each of them also do seek in file and lock/unlock functions. And because
it is on Linux native partition, these I/O go over INT2F network redirector
too. Tried You run this app under Windows from remote share?

At these short interval it maybe OK.

Re: Dosemu Slower than CMD

[Frantisek Hanzlik]

As I wrote in my previous mail, in tested program segment is about
200000 times called INT0x16 Fn 0x11 : Check_Enhanced_Keystroke.
In corresponding dosemu routines in "base/bios/int16.c" are called
some delay functions - maybe these may add some delay to program
execution.
On my system CLK_TCK=100 (ticks/sec), thus JIFFIE_TIME=10000 and
INT2F_IDLE_USECS=80000 (=> 80msec delay).
But as I wrote, on my faster PC exec time was 3 sec, thus delay
added in INT16 can't be longer.

Bart Oldeman probably can say more about this.

Re: Dosemu Slower than CMD

[Eddy Setyawan]

hello Frantistek,
Which segment you try ? I mean slow is at menu Master -> Persediaan ->
Ubah Harga Jual, while entering this section application cpu usage
jump to 100% and waiting to load all data is takes time than CMD
does... even at windows i try it with shared drive

some alert dialog also eat CPU but after search around i found that
clipper function for alert dialog has some bug

CPU load I not measure, but as I said, 100% load may be OK.

Note I must set DOS date to March 2008.

Re: Dosemu Slower than CMD

[Frantisek Hanzlik]

I just haven't no win machine, then I can't compare program response under
them.
However You can compile dosemu with log timestamping (see conditional
compilation  and SHOW_TIME and DBG_TIME identifiers in module
"src/base/misc/utilities.c") and try find Your application/dosemu code
bottleneck.

IMHO when Your app do any sort of intensive DOS/BIOS calls, then differences
between DOS/win and dosemu speed may be noticeable and scale 1:3 - 1:5
may be "normal", as their appropriate environments are different.

You may also tried Your app under clear FreeDOS or other DOS environment.
