I agree, external connection could be an issue here since Sling does return back HTTP to the thread pool. One quicker way to know all this will be taking 20 thread dumps every 500ms and then going through those which are running or in waiting state. Hopefully you will get something interesting there. However one thing I would like to know- what is the thread pool size configured in this server?

Hi Feike,Yes that is the approach, we have taken so far where-in we are storing ClientLib name at page property and then using inheritedPageProperties, getting this value to do a cq:includeClientLib. But as you see, to make this working author has to set 2 properties to make this work- design path and then clientlib name, also this looks to me a custom clientLib resolution. Since Design path is the one which looks to me more appropriate as we are talking about swaping one design vs. other here, ...

Thanks so much Feike. Appreciated.Good to know that we can swap clientlib at template level but my question was more specific to a content hierarchy. Would this suffice that use case as well? Consider a brand having multiple themes- men, women and kid and giving the option to author to choose specific clientlib for men sub-hierarchy than women. Also even if this work why to marketer 2 different configurations- one for design path and other for clientlibs while both could be driven by a single pr...

IMO, Clientlib makes sure that even if you include a clientlib multiple times, only one of its instances will be converted into tag, so long as Category name is same.Apart from dependency management challenge, I believe another issue will be a number of HTTP calls going up now since every component will now try to get it's JS file when it tries to render which could be a performance issue in HTTP 1.1 and how browsers work.I would recommend going with template specific clientlibs since you will have less number of templates but more pages and browser will be easily able to cache it on the very first page using that template. Template could be as hardened as possible for example asking the designer to lock what all components can be part of this template. This approach is more inline of your #3 approach.

Thanks Ove. That makes sense if configuration is same. My use case is slightly different which is without making my service aware of configurations, I want it to pick two different set of configurations. In your solutions then service factory should first figure out and load the correct configurations and then pass it to the service. If I have more services I will end up having service factory for all. And also the responsibility which I am giving to servicefactory class around configurations sh...

Use case is in my first post. I was not talking about changing runmodes above since this can not be done, what I meant was using the same api which picks the right folder based on current runmodes. I was wondering if there is a method which takes string array (runmodes) and give me the configuration based on a PID. I am sure CQ must be using some sorts of API itself to load and cache the configurations.

Thanks Ameesh. I know CQ ootb runmode works that way and it is fixed. I was more looking for hooks/extensions to change it at run time. I would assume folders are to be picked by some apis and was hoping to use that or extend it. Also I don't want configuration to be changed by another code because it will be too risky since all these configuration defines my system behavior. Please let me know if you want more information.
