>Hi. I have used vfp with COM+ for a low usage intranet knowledgebase before with no problems but I am looking at designing a site for internet use that will have high traffic. I have heard that VFP has too much overhead to be hammered in COM+ vs some other low level language such as C. Anyone do extensive work with vfp multi-threaded dlls in COM+ or in .NET that can offer
>some suggestions?

Peformance of VFP COM MTDLLs is very good, but as with anything it depends much more on what type of application you build, what types of queries you run etc. Load management has much more to do with the actual application, than the architecture...

That said, VFP COM objects can serve over 100 requests a second easily. The biggest issue IMHO with COM in ASP is that it's a bitch to debug and administer the applications especially if you're not familiar with COM and COM administration/installation.

COM components from ASP.Net have the same issues, but there there is additional overhead for calling COM objects plus the import mechanism can make using complex hierarchical objects much more work than with classic ASP. If you're interested in this take a look at:

and look at the ASP.Net/VFP COM interop article which has many details on this topic.

I don't think you want to write a Web site in C++ <g> and in terms of performance VFP stacks up well against other environments in most situations. THe exceptions are if you run lots of long queries and use native Visual FoxPro data to do it as that will tax the server hardware very heavily.
