On sforce’s performance and scalability …

Simon Fell > Its just code > Share and Enjoy

a completely new SOAP stack …  was written from the ground up purely to be Salesforces server side soap processor, its is extensible just enough to do its job and no more (many soap tools are extremely extensible, and it comes at a considerable cost), we concentrated hard on perf both response time and scalability. The open source soap stack that we used previously has particularly bad scalability issues, it uses a lot of memory to process a request, which leads to a high level of GC related load, and a reduced concurrency ability from transient out of memory exceptions. Reduced GC load is good for us, and improved response times are good for you, in some testing I did I saw response times (for the entire request not just the soap processing part) as much as 50% faster than the earlier stack.
