Besides code cleanup, another advantage is that the preliminary benchmarks tell me that the performance and scalability will be quite something.<BR/><BR/>The project will be available soon (2-3 weeks) for download and will be open source.<BR/><BR/>Stay tuned...Igor Minarhttp://www.blogger.com/profile/03520548417275543432noreply@blogger.comtag:blogger.com,1999:blog-6406593750327945950.post-87141575213757324342008-09-01T16:17:00.000-07:002008-09-01T16:17:00.000-07:00Thanks for the great post.<BR/>About the servlet filter w/ fake HttpServletResponse. How do you implement it? Is it written entirely in java, or can you call ruby code from there. It looks like an alternative to BackgroundRB living inside the same server, which is very good.Jose Murillonoreply@blogger.comtag:blogger.com,1999:blog-6406593750327945950.post-13989573309798411342008-06-12T14:13:00.000-07:002008-06-12T14:13:00.000-07:00We started using JRuby on Rails too. Where the MRI garbage collector just crashes and burns, the JVM GC really shines. We had one government application which was rather leaky and JRuby just cracked it.

I think that you are doing great with your oracle mix app. Congratz!<BR/><BR/>@jurassicGeek: You don't need to worry much about the CPU speed, depending on your application specifics and if you really want this to be your production server, you should consider upgrading RAM. I'm not a sales person, but from what I hear Sun's HW is not considered expensive any more. In addition to that there are some great programs through which you can get some awesome deals.

I think of combining the RoR app in Glassfish with Comet. But in case of success (many concurrent users) i think our Dedibox won't support it, because of its small capacities... perhaps should we think about Cloud Computing with Amazon for scaling, without paying too much (Sun Servers are too expensive for us ;-) )...jurassicGeekhttp://www.blogger.com/profile/06712782766370638731noreply@blogger.comtag:blogger.com,1999:blog-6406593750327945950.post-91289579048097942252008-01-30T10:57:00.000-08:002008-01-30T10:57:00.000-08:00Glad to see Sun deploying on JRoR!

There were quite a lot of additional work on JRuby 1.1 to fight memory leaks and reduce the memory pressure, not to mention aggressive performance optimizations. So, hopefully, transition to JRuby 1.1 might bring some additional benefits. :)Vladimir Sizikovhttp://blog.emptyway.comnoreply@blogger.comtag:blogger.com,1999:blog-6406593750327945950.post-23619872912752099622008-01-29T00:21:00.000-08:002008-01-29T00:21:00.000-08:00Nice project, congratulations!

Nobody expected this to be a project without risk, but experimenting with new technologies, goes hand in hand with taking a risk.
