Paul, I assume this is 32bit given the amount of RAM. If by 750 pages per second (bursts up to 1250-1500) you mean ColdFusion templates executing (and I assume you do) then you are getting quite a bit out of the server I'd say and making good use of your xeon 3.3's :) Your options for tweaking are going to be fairly limited - perhaps some tuning with how GC operates or changes to the simultaneous request number - and of course caching (queries or structs or whatever you are using repetitiously). But all in all that's pretty good for page executions per second. Note - page executions are not the same thing as http requests... 750 http requests could well be quite modest. Most http requests are NOT for cf pages but for css, images, js etc.
Also I would add that it is often the performance of the database that determines the capacity of the web server. It sounds like you are doing ok with that as well.

I'm currently experiencing stability issues with CF 8 standard due to what I think is high traffic loads on the sites its running. There are 6 sites on this particular instance of CF8 and collectively they're averaging at around 750 pages per second which result in around 6000 SQL queries per second (that's queries, not transactions) when measured over a peak 24 hour period. At peak times (just before and just after lunchtime) then I can see as many as 1250-1500 pages per second and 10,000 to 12500 SQL queries per second. It's at these peak times that CF starts to queue requests and then restart. Clearly this is not desirable but I haven't got any numbers to compare it with to see if I'm hitting CF's limits on the hardware available to it or whether I can or should be tweaking the CF code and JVM some more. For comparison, a normal 24 hour period is characterised by an average of around 200 pages per second with around 1500 queries per second and CF has no problem with that. The sites in question are job sites so there's a lot of searching going on using K2 and SQL to merge aspects of the jobs with geo-location data such as distance from a postal/zip code. As you can see from the numbers there's an average ratio of 8 queries to 1 page request which I believe for the site is pretty lean. Do any of these numbers look out there. Is anyone else running these numbers (or higher) on a CF standard install? Hardware wise it's running on a DELL PowerEdge 2650 with 4GB RAM and Dual Xeon processors [email protected].
