SQL Server: How to insert million numbers to table fast?

Oct 30, 2010 · Denzel D.

I don't think ORMs support something like this easily. Or at least there is no built-in way for that. ORMs that give you out database connection they are using allow you to execute your own custom queries against that connection. When you use ORM you should always be ready to execute also some database specific code directly.

Three approaches to JRuby GUI APIs

Sep 26, 2010 · Mr B Loid

If you read the title of post then you should see what is topic. I have made no statements that these measurements are the only thing or most important thing about DI/IoC containers. Pro developers often measure how their tools work and this is just one usual measurement. I thought the results may be interesting also for wider audience.
Plus or minus couple of seconds is just one case. It really depends on how application is built, how much data it has to handle, how many users or processes are using etc. Your win may be second or two but your win may be also less or more. It depends on many factors.
Comparing features in neutral way without causing another pointless flamewar is good idea. But it is very subjective topic. Measurements are different because they are over all religions. As soon as I have better picture about features of different DI/IoC containers I will write post that compares their features and implementation details.
