Hi, We've hit a snag, and really hoping someone here can help. Hopefully there will be some consensus about what the issue is! We've been working on a new web application. We've been running the UAT on a server with Rackspace (shared space with the team doing the dev) Yesterday, we pushed the web app to the live server for a soft launch. It's a dedicated server with Fasthosts. There is a noticeable discrepancy between the performance of the UAT and Live sites. We updated the admin site with the main code disabled (our code doing almost nothing) and the Live server is 3x slower on average than UAT. The stats below show the time taken to complete the same task on UAT and Live (see images with green bars and time in seconds highlighted). But our code is doing almost nothing in this test, so it implies that something in-between the browser and the web server seems to be slow. We're not sure, But possibly this would point to something in the network or server infrastructure. Comparingthe Rackspace server (on UAT) with the Fasthosts server (on Live) with the actual software the same in both cases we pulled the CPU and Memory details. On the face of it the live server should be as fast or faster than the UAT. We're no expert on these stats but it's interesting that the 'Speed' is showing 1.17GHz on the Live server, even though the CPU is supposed to be 2.20GHz. Whereas on the UAT server, the 'Speed' is showing 2.88GHz, even though the CPU is supposed to be 2.40GHz. I've pasted the screenshots of the CPU and Memory for UAT and Live servers below, along with the time to save a question on UAT and Live (3x slower on Live). It is interesting that the 'Speed' showing on Live (1.17GHz) is almost 3x slower than the 'Speed' showing on UAT (2.88GHz) so that tallies with what we are seeing. Any help would be appreciated. Hopefully I will be buying one of you a drink soon to say thanks!
