Are you serving .SWF files from your web server and getting complaints from your end users that your flash app is "just slow?" Or has your Ops team wondered why you see such high web request response times for some of the web service calls executed by your Flash Client?
I was just working with a bank that uses a Flash Component for one of their internal risk management applications. For years they wondered why users were complaining about very slow response times when executing, e.g., a "Credit Worthiness" check. Our teams helped them figure out the root cause of the performance problem: "Back in the day" they had turned off Apache's Content Compression (MOD_DEFLATE) in order to avoid a known issue of content compressed flash files that are content compressed. Unfortunately they turned it off completely and not just for .SWF Files. So - all other requests - especially the heavyweight Web Service Responses were not compressed.
After selectively turning on content compression they are now seeing a 50% improvement in overall response time; 70% reduction in Apache and a 92% reduction in transferred bytes. Here's how they analyzed and solved the problem:
Step #1: Identify the Slow Requests
Looking at the captured PurePaths it was easy to spot that most of the time (2/3) was actually spent in the Web Server and not in the App Server:
8.1s alone are spent in the Web Server to send the content from the App Server back to the End User
But why 8.1s? That's a long time spent for mainly just I/O (e.g., reading and writing to the network). Looking at the request details shows us that not only did this call come from a Flash Component (Referrer Header) but that the response size of that request was 2.25MB. As this web request is called very frequently and other requests also tend to have a very large response body, network bandwidth becomes a problem, which results in lots of time spent in I/O when sending back the content to the browser:
2.25MB in Response Size is the driving factor for the slow web server response time

As the world moves toward more DevOps and Microservices, application deployment to the cloud ought to become a lot simpler. The Microservices architecture, which is the basis of many new age distributed systems such as OpenStack, NetFlix and so on, is at the heart of Cloud Foundry - a complete developer-oriented Platform as a Service (PaaS) that is IaaS agnostic and supports vCloud, OpenStack and AWS. Serverless computing is revolutionizing computing. In his session at 19th Cloud Expo, Raghav...

In today's uber-connected, consumer-centric, cloud-enabled, insights-driven, multi-device, global world, the focus of solutions has shifted from the product that is sold to the person who is buying the product or service. Enterprises have rebranded their business around the consumers of their products. The buyer is the person and the focus is not on the offering. The person is connected through multiple devices, wearables, at home, on the road, and in multiple locations, sometimes simultaneously...

Fact: storage performance problems have only gotten more complicated, as applications not only have become largely virtualized, but also have moved to cloud-based infrastructures. Storage performance in virtualized environments isn’t just about IOPS anymore. Instead, you need to guarantee performance for individual VMs, helping applications maintain performance as the number of VMs continues to go up in real time. In his session at Cloud Expo, Dhiraj Sehgal, Product and Marketing at Tintri, wil...
