Understood your point about the catch. One more problem I am facing is that even when this part of code is executed second time. Let's say after launching the application for the second time it is still taking the same time when not using reference.

But there is a catch. The framework assumes that the code that is doing the installation of the bundles with 'reference' scheme is controlling the content of the bundle such that it will not dynamically change (get overwritten with new content or deleted) without either doing an update call (in the case where you override the file) or an uninstallation call in case you are going to delete the file. Unspecified behavior will occur if you change or remove the content of a bundle file that the framework is actively loading out of.

So with 'reference' install i am getting a huge performance improvement. So is it the case? or its just that I am dealing with a badly written code :| I have some 700 jars in a folder that and its not fixed can be added/removed by the user. The code is written as such it will loop over the list of jars present in the directory. Install the bundle one by one. If the bundle already loaded then it is uninstalled. Currently, 'reference' is not used. But with 'reference' I got a huge performance improvement. Is it expected?

Instead it will load the bundle directly out of the file URL the 'reference' URL is pointing to. Note that 'reference' URLs only support embedded 'file' URLs (not http etc.) This has advantages for management agents that manage bundles in their own bundle store on disk and you want to avoid double copies of the bundle on disk when they are installed into the framework. Any non-reference URL will copy the content of the bundle into the framework's internal storage. This allows the original content to be deleted after installation and the bundle will remain functional and installed within the framework.
