I just realized this is awesome news actually. At the moment, the code is aways waiting for the callback before going to the next one: Every call to storeManager.persistMessage will only return when the callback is returned, or the message is persisted on disk. If this is performing as fast as noSync already.. this is great.

OK, got it. The maven file name is wrong, The most recent artifact contains on older timestamp in the filename then the previous one. | 0.1.0-20080506.155037-61 | 0.1.0-20080507.084835-60 | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4149449#4149449 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4149449

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: To UTF-8 or not to UTF-8 that is the question

by david.lloyd＠jboss.com

Just use UTF-16 encoding. You basically get this for free if you are just writing out chars. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4149445#4149445 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4149445

If so, then we can programmatically set the java lib path and no conf is necessary? I have tried (without much success) to compile libaio statically. I'm still trying. But I would be concerned about redistributing libaio in our packages, since it is a OS dependent package.

I don't really like the idea of users having to set env properties to get our software to run. It's messy IMHO. The only way around would be to install the library on /usr/lib, and we should have that when we have the RPM or .DEB package.

[Design of Messaging on JBoss (Messaging/JBoss)] - To UTF-8 or not to UTF-8 that is the question

by timfox

JBM 1.4 uses UTF-8 encoding for all strings sent in messages, e.g. properties, text message bodies etc. This provides a good compression if using higher unicode characters a lot (e.g. chinese), however the java UTF-8 encoding is *really slow*. For JBM 2.0 we're currently the SimpleString class I wrote (which doesn't copy itself on the drop of a hat like String) and we marshall it as a simple sequence of bytes. In my tests this is about 40 times faster than UTF-8 encoding the same string. :) Problem is SimpleString currently only stores each character as two bytes, which is fine for the vast majority of unicode characters but won't encode the far reaches of unicode which require 4 bytes. I can change SImpleString to use 4 bytes per character but this is going to make the marshalled form big - especially in the case of standard latin characters or european - about 4 times the size as encoded! How do you think we should deal with this? One possibility is we write our own UTF-like encoding implementation...
