Offer HN: Performance and scalability design for non-cloud environments

Do you have performance and scalability problems you can't 'throw enough hardware' at ? If you still keep control over all your application's parts -- operating system, web server/app server, run-time and database -- and simply can't solve performance bottlenecks by acquiring more dynamos, EC2 instances or other cloud-type services. I can help you. I'm in the middle of writing an on-line book covering performance and scalability topics on web applications and I'm looking to add issues and solutions to multiple problems. I have over 10 years of experience in this area. So if you have these type of issues, send them over. I can help you solve them and it can aid me in creating more thorough content. In particular, I'll field questions on: * Slow queries or Object Relation Mapping to RDBMS. * Web servers, reverse proxies, file systems and operating system level tuning * Caching topics for an application's multiple tiers. * Slow application code (e.g. sorts, search, parsing) You can send your questions to the email: performanceqa@webforefront.com The online book is published at http://www.webforefront.com/performance/ in case you want to read what's already published.
