Determine memory used by asp.net cache in shared hosting

Question

According to this question, I want to know if asp.net\'s system.web.caching.cache is good for me, or I should use database caching?

So, I need to know how much memor

Answer 1

One fast way to see how many working memory your application use is to direct ask the garbage collection.

long bytes = GC.GetTotalMemory(false);
txtMemoryUsed.Text = bytes.ToString();

and use this literal <asp:Literal runat="server" ID="txtMemorysUsed" EnableViewState="false" />

But you can get more details using the PerformanceCounter, for example you can get how many virtual memory the pools used by this code:

 var oPerfCounter = new PerformanceCounter();
oPerfCounter.CategoryName = "Process";
oPerfCounter.CounterName = "Virtual Bytes";
oPerfCounter.InstanceName = "aspnet_wp";
txtMemorysUsed.Text = "Virtual Bytes: " + oPerfCounter.RawValue + " bytes";

You can use all this parameters to get information's for your pool.

Processor(_Total)\% Processor Time
Process(aspnet_wp)\% Processor Time
Process(aspnet_wp)\Private Bytes
Process(aspnet_wp)\Virtual Bytes
Process(aspnet_wp)\Handle Count
Microsoft® .NET CLR Exceptions\# Exceps thrown / sec
ASP.NET\Application Restarts
ASP.NET\Requests Rejected
ASP.NET\Worker Process Restarts (not applicable to IIS 6.0)
Memory\Available Mbytes
Web Service\Current Connections
Web Service\ISAPI Extension Requests/sec

for example, this parametres get the cpu load.

oPerfCounter.CategoryName = "Processor";
oPerfCounter.CounterName = "% Processor Time";
oPerfCounter.InstanceName = "_Total";
txtOutPut.Text = "Current CPU Usage: " + oPerfCounter.NextValue() + "%";

I have test that on local iis and works.
