The general theme seems to be "performance is acceptable given the power of NHibernate". I don't mean to be antagonising, but that's an unfair summary of the problem. There are many other ORMs who have a comparable featureset but with different performance characteristics, and for the rest I'm not even aware of any quantitative analysis of the value of some of the more tertiary features vs their performance impact.
My point is not that someone use up their free time and respond voluntarily to kick the ass out of the performance issue on this free product. I work on an OSS project; it would be hypocritical (and we use NHibernate). I'm talking about comms, and humility. It can lead to tickets like this remaining untouched for years https://nhibernate.jira.com/browse/NH-1365 @Harshil, for the moment if you're unhappy with NHibernate performance in your scenario, take a look at something like PetaPoco *Alex Norcliffe* Lead Architect, Umbraco 5 Microsoft Regional Director @alex_norcliffe <http://twitter.com/alex_norcliffe> on Twitter, blogging at boxbinary.com On 20 March 2012 09:44, Mark Cranness <[email protected]> wrote: > On 19 March 2012 16:46, Chinna <[email protected]> wrote: > > I have been evaluating the performance of NHibernate and ADO.NET.
