We're looking at throwing more hardware (both upgrades to existing servers as well as new or replacement servers) at our mix of applications to improve performance. I'm looking for insights from personal experiences on a couple of approaches. Our application mix that needs the performance runs mostly between midnight and mid-morning, and is a suite of CF scripts that interact with webservices from the major search engines. Lots of XML parsing and processing with lots of database activity to store the data. Some of the XML files are large, and therefore use up a lot of JVM when being processed (since at some point in time there needs to be a copy of both the CFHTTP data returned from the webservice as well as the structure being created by the xmlParse function). We have a pretty well configured SQL 2000 server, although the production could admitedly use some tuning. These are Windows servers, so we have the inherrent limitation of ~1.8gb address space, which boils down to around ~1.4gb available for the CF apps running in the JVM. >From a processor perspective, what are people's experiences on the topic of >multiple processors versus dual-core/quad-core processors?

What about just running a stack of multiple servers? This helps solve the Java/CF memory space problem. What about just running a stack of multiple (cheap) workstations, possibly with dual-core processors, instead of a big honking (expensive) server (we'll call this the Google approach)? What about virtualization? Any experiences using either Microsoft's software or VMware on a server with an instance of CF on each of them? That also solves the memory problem (presuming sufficient physical memory), but would seem to be highly sensitive to the number and effectiveness of the processors/cores. It seems like it might have an administrative advantage over simply running multiple instances of CF on the same server since I wouldn't have to worry about port numbers and such on the same server, because each would be running on port 80 on its own IP address within the virtualized server. Any other alternatives? I can definitely find additional work for these systems to do during the daytime, but the real crunch is to get all of that XML data processed by CF during the nighttime before people show up in the morning.
