Perfomance Monitoring

I assume,in DASP's shared server environment, that a DASP clientis limited in terms of access & use of (IIS or other) performance monitoring tools, for example to determine "performance bottlenecks" (particularlyprocessing or memory intensive applications)that might point to sub-optimized code/memory use.

Iassume the general idea is any "performance monitoring" and code-review by the developer takes place before prior to deployment (using their local IIS and associated tools).

Still,this leaves open the question of how performance might be extended/scaled/degraded as a result of DASP configuration policies or operating rules.

Maybe I am wrong in my assumptions:

(a) are there "performance monitoring" tools (I don't mean "LiveStats", raw logs) accessible on discountASP for client use?

(b) are there guidelines/experiences that one should be aware of that a developer could factor in towards a "performance expectation"? For example, somewhere I thought I read that each discountASP account gets a memory partition of 100Mbyte and that memory inefficiency might lead to degraded performance?
