It was Prabhat Singh who said at the right time 25.09.2008 11:44 the following words:
I am trying to run old version of Aperture (Alpha). I have written a program to spawn multiple threads and each thread is capable of running aperture's crawl().
usually we do not support old versions,
and investing time into looking at it is costly.

is the behaviour the same in the latest-from-svn?


private class SimpleCrawlerHandler implements CrawlerHandler, RDFContainerFactory {


I did this to extract content from multiple directories simultaneously, on demand. However, I am seeing following two problems:

1- If I send multiple simultaneous requests, seems there some serialization happens somewhere and the through-put is not linear to number of threads, insteads, if I increase number of requests, the throughput of the crawler decreases significantly.

2. I want to extract the content of the files and then discard the model. However, even after calling clear()  API and forcing Garbage collection, I still see continous increase of Java's memory after each request is processed.

Some of these might have been solved in newer version. But. I do not have the choice to move to the newer version of aperture and I need to fix these issues in the alpha version only,

Any suggestions / directions will be highly appreciated.
