Re: OT: Better Java performance on Linux
Inge Solvoll [EMAIL PROTECTED] wrote on 16/01/2007 09:53:50: A friend of mine (big linux fan) told me that tests at his workplace indicated a huge (up to 500%) java performance gap between linux and windows snip Has anyone here experienced anything similar, with either OS performing vastly better on any java task? Is the gap widening or closing with newer versions of Java and OS? The reason for this is probably that the windows version of Sun's JVM is set up with defaults for memory sizes and garbage colletion algorythms which are optimised for a desktop pc, not a server. All of these options can be changed manually, and a true comparions can only be made where both instances are set up with the same values on the same hardware. At a simple level using -server on both will narrow the gap, but only a good knowledge (and a refrence book) will ensure that the two things are the same. You should tune your server processes, and refine your applications, according to the resource use that you measure in tests and in the wild. I'm sorry I don't have a refrence for you to look at, but you might like to look at my slides from apacheconEU06 at which I talked about Garbage collection tuning. d. *** The information in this e-mail is confidential and for use by the addressee(s) only.

Re: Re: Re: need please wait notice for slow loading pages
if you can get the first bytes of the second (slow) page loaded you can
start that page with the html for a div to appear in the centre of the
screen in front of the real content.
The last thing on the page should be the html which moves this either away
to the left (negative coordinates) of the screen or to the back behind
the real content.

reader) :

Unfortunately, my problem is that I need it on plain links as well as
in forms. Nothing I can't fix by just assigning a new class to any
link that needs the handler and then adding the handler via a
javascript method which iterates over all elements with the
'pleaseWait' class.

Re: Tapestry 5 Discussions
Howard Lewis Ship [EMAIL PROTECTED] wrote on 01/08/2006 17:34:47: snip/ I tend to agree with most of what you said. The central issue is backwards compatibility. As the upgrade from 2 to 3 to 4 has shown, adding new features to Tapestry often breaks existing code. This is a reaction to the relationship between the framework code, and the application code. The fact that application classes extend framework classes means that virtually any change to the framework classes exposes client code to incompatibilities. Yep, this is the key issue at stake, and in fact it also appears to manifest itself as unnecessary inflexibility and constraints on component development. Changing this is a clear benefit, no doubt about it. I've forced people to choke down the poison pill in little stages, from 2 to 3 to 4. I don't expect that to happen once 5 is out ... the annotation-based APIs are wonderfully flexible and adaptive even when the framework is changed. That is a welcome positive message. My goal is not to beat JSF, but to give Java developers a compelling reason to stay on Java and not jump over to Ruby on Rails. That's a tall order. With all due respect the way you need to go about that is to capitalise on the loyalty of your existing users, support us in achieveing our sucesses with Tapestry and we'll promote your project, no question. I don't underestimate the effort required to provide a migration path, but neither should you underestimate the value of retaining your existing users. The two features of Tapestry which really sell it into a commercial enterprise are 1) reuse and 2) the excellent separation of concerns between HTML functional programing. To have no upgrade path at all would be to remove 1 as a benefit for existing users. I'm pretty sure that people will step up and contribute to an effort to provide backwards compatibility and upgrade tools, there is clear self-interest there to motivate us, but only if we think you guys really buy into the nesessity of it, and can convince us that it will be a once-and-final big-bang. Otherwise JSF, ruby on rails, even Oracle ADF, or any damn thing out there, will be seen as no more of risk or an effort to move to than sticking with Tapestry as a strategic choice will be. We have made the strategic decision to use Tapestry please don't make me change it. Those of us who have a broader view of product selection than technical excellence alone, we have to take into account the cost of ownership, will be hard pressed to continue to justify our decision if we don't have some kind of assurance that this really is a final one-off cost. Your earlier statement goes some way towards that I'm glad to say. Brian McCallister gave a great presentation on managing open source at ApacheconEU 05, (slide are here [1]) one of the key messages he made, and which is reinforced by the principles of schemes like CMMi and ISO9000 is that evaluation of OSS by commercial users must take into account the predictability stability of the project and the ease of engagement with the community. Clearly documented roadmaps and statements of intent, and support for user-led initiatives are whats needed now if you want to pass those tests. Get behind and promote an effort to provide a migration path, no one expects you to do all of the work just to promote it, set out and end-of-life timeline for Tap3 and 4, document your decisions and I'm sure we'll stay with the programme. d.

Epstein, Ezra [EMAIL PROTECTED] wrote on 01/08/2006 21:31:27: Rather I was questioning how the decision about IoC adoption is being made. At the time HiveMind got started the IoC container space was pretty open and empty. I don't really think thats true at all, but Hivemind did have some advantages over the competition, mostly the fact that it had been designed by Howard as the IoC provider for Tapestry. Of course Spring lacks features needed. Understood. Could Spring be extended? I find that quite hard to believe, more likely those who are saying so don't have the experience of Spring required. Of course it might still be *difficult* to use Spring for Tapestry IoC, but that is a different issue, and as Spring is an OSS roject too there is little doubt that the Tapestry team could engage with the Spring guys to work out whats needed. The trouble we all have -- it is certainly not unique to a creator of software or this software -- so I'm speaking of my own experience, is that I (and most folks I know) tend to get a bit skewed in favor of things that are our babies so to speak.

Re: Tapestry 5 Discussions
Finally, let's take a sober look. Of all the production apps written in T4, how many do you REALLY BELIEVE would be ported to T5? I'd say 1 of a hundread, if that. On the other hand tapestry provides us the the ability to re-use components. If we want to write new applications in Tapestry5 do we throw away all our old components and lose their value? Or do we go to the expense of migrating them and writing new ones? For the people who are stuck requiring support for product which is likely to be ending its life the choice will be a stark one, not whether to upgrade to Tapestry 5, but what framework to migrate to. I would predict that most of the people who see their investment in components become increasingly worthless will have little loyalty left and will plump for something which is more likely to protect their investment, no matter what the technical limitations are. Look out for people offering a Tapestry4 to JSF migration path. d. *** The information in this e-mail is confidential and for use by the addressee(s) only.
