Subject Re: Anyone using OSGI bundles for high volume OLTP applications
Date Fri, 14 Mar 2014 13:46:53 GMT
Indeed, OSGi can improve the performance of classloading because it reduces the search space.

Looking up service references can add a small overhead. However this is usually done very
infrequently, with the result being cached until the framework notifies us of a change.
