I'm looking at moving a Magento installation between 2 servers, this is in a shared hosting environment hosted by Nexcess.net
In this instance, the site will be moved from a SIP100 server to a SIP200 server (you can see the specs here: Nexcess - Magento Shared SIP Hosting Plans), pricing difference of $55. (Which is about a 120% increase in pricing).
In terms of performance, I only see the 8GB more RAM as a benefit. My main interest is the support for Redis cache & memcached. I'm going to set up the store to use redis as the primary & slow backend cache, and use memcached for sessions.
I've read some articles which suggest that Siege may not be the most accurate tool to test Magento performance.
I've tried a few options, i.e the profiler, timing scripts & using siege tests.
Are there any other efficient means of benchmarking your Magento store's performance?
P.S I'd really also like to test the backend performance.
