Hi gurus,

Can anyone tell me please when I really must setup the value of memory that
aspnet_wp or w3wp must use in IIS server machine?

What I mean is that we have clients that have diferent specificatiosn in
their server machines that have IIS to runnning WebApplications. This can
change for example in RAM memory that is available. One have 1GB, other 2GB
and another 4GB. I.e., how can I know when I must change any configuration
in machine.config or even in IIS (at this case only in version 6.0) to limit
the memory that ASPNET process must use. I know the default value is 60% of
memory RAM, but is this ok in a 1GB memory RAM machine as it is ok in a 2GB
or 4GB memory RAM machine. Personally I don't think, but when can I change
this value?

I'm asking this because I have a client that have 2GB RAM and the aspnet
process grows until 1,3GB and then recycle (after some days of use, there
are 1800-2000 users using application). The problem is that this client have
other applications working there and the server not response efficiently to
requests when the process have this value. I should say that my WebApp use a
COM on some pages object and for that I'm using ReleseComObject. I should
say too that this WebApp is installed in a CLUSTER (may be this have
implications, I don't know).


I already run Profilers, windows performance for aspnet_wp, and mutch
more...

What do you sugest to do? Do I must limit the memory value that aspnet
process use to some value?
Where can I get more information of this (if possible from microsoft) to
present?
