I need to build or buy an application that will allow me to generate a
specific CPU load and memory usage. Ideally I could throttle this up and
down to simulate different load conditions. This for application testing -
we'd like to see how the app performs under certain load conditions.
I'd prefer to build it myself with C#, mostly just for the learning
experience and because I have the time.
Has anyone done something like this? I'm looking for suggestions, links,
and info to help me start investigating the namespaces I might need or the
approaches I might take since I'm not exactly sure where to start.
I know I can use the System.Diagnost ics namespace for monitoring cpu load
and mem usage, but I'm not really sure how to approach loading the CPU and
memory so that I can throttle it up and down.
Thanks in advance for any thoughts. 4 11441

Some quick code:
public static int Fac(int n)
{
if(n 1)
{
return n * Fac(n -1);
}
else
{
return 1;
}
}
public static int CpuTime()
{
return
(int)Process.Ge tCurrentProcess ().TotalProcess orTime.TotalMil liseconds;
}
public static long WallTime()
{
return DateTime.Now.Ti cks / 10000;
}
public static void Load(double target)
{
int n = 1000000;
int cpu = CpuTime();
long wall = WallTime();
int dcpu;
long dwall;
for(;;)
{
for(int i = 0; i < n; i++)
{
if(Fac(10) != 3628800)
{
Environment.Exi t(1);
}
}
Thread.Sleep(10 0);
int cpu2 = CpuTime();
long wall2 = WallTime();
dcpu = cpu2 - cpu;
dwall = wall2 - wall;
n = (int)(n * ((target * dwall) / dcpu));
Console.WriteLi ne(dcpu + " " + dwall);
cpu = cpu2;
wall = wall2;
}
}

Drop that line.
It was just for verifying stability.

That may do it, thanks for the replies. I'll be working on it this week, so
I'll give it a try.
Thanks,

Hi,
i create my GUIs mainly via wxGlade. However when you start of to

your file and you've got to put your own code back in.
I think i can work around that (at least a bit) by making a second file
that imports the gui generated by wxglade and make classes that extend...

Hello,
I need to change collation in my database (more databases acctualy).
Therefore, I wanted to make a script, which will do it at one more

I already have a cursor, updating collation on all tables (fields) in
database.
The problem is, before I will to update the collations, I need to drop
all constrains and pk's.
