Peak performance and server load testing

[cmeurer]

What kind of order throughput can I expect on a 2 cpu Xeon with 4 GB ram? w Raid.
What kind of page views per hour, orders per hour, hits per hour etc?

Similar topic different Question. What type of benchmarks would best show how well your server will run Able? Some of my pages take a bit to load but im not sure why?

That post dealt more with catalog structure than with order throughput. About how many products would be in your store catalog?

Well we are really looking for any guidance on capacity (orders, SKUs, concurrent users, customers, etc.). Pretty typical dual core hardware.... cm

Load tests are always difficult. There are so many variables that can affect performance ranging from machine configuration to external latency (e.g. third party shipping gateways). But I ran a quick test using our sample store data on this machine:

AMD Athlon 64 X2 Dual Core 6000+ 3GHZ
3GB Ram
Windows Vista
Local SQL 2005 Express

I load tested a checkout sequence:

add product to basket
view basket
checkout

All together the sequence involves 3 GETs and 4 POSTs. The machine was able to process approximately one complete checkout sequence per second. It was running at 7.03 requests per second (422 pages served per minute).

This was done with a sample of 20 concurrent users. Most importantly, not a single checkout was dropped or errored. This is of special note because AbleCommerce 7.0.2 has a fully transactional checkout sequence with a retry logic. Under high load, contention for resources is a reality. AC7 is able to respond accordingly.
