I did some profiling of Transfer on CF9 vs CF8, and transfer was a lot slower on CF9 in tests caused a lot of new objects to be loaded from the DB (ie, cache exhaustion).
I suspect this is due to the fact that transfer has some custom code for CF8, and treating is CF9 as CF7. MM confirmed this may be the cause at CFObjective. The results were very interesting, with Hibernate performing a lot better then transfer under load. I can post comparisons of transfer vs hand-coded objects vs hibernate on CF8/CF9 if you like (obviously no results for hibernate on CF8). The clear winner was Hibernate, followed by hand-coded objects, then transfer. dave On Feb 5, 5:53 am, Brian G <brian-goo...@vfive.com> wrote: > Assuming you've upgraded your CF8 JVM beyond the classloader issue, > can anyone estimate the performance improvement for Transfer-based > apps from upgrading to CF9? > > I'm familiar with tests like Jamie Krug's object creation test but I'm > more interested in what kind of actual impact that CFC creation > improvement has on your app. E.g., on the same hardware, same app, > same load, etc, what kind of a performance boost, if any, did you see > in upgrading? > > Ballparks and gut feels are ok with me, thanks! > > Brian -- Before posting questions to the group please read: http://groups.google.com/group/transfer-dev/web/how-to-ask-support-questions-on-transfer You received this message because you are subscribed to the Google Groups "transfer-dev" group.
