Subject Re: Crawling and indexing very slow
Date Thu, 31 Jul 2014 18:13:13 GMT
Hi Ameya,

(1) Please look at the Simple History report.  Note what kinds of documents
are being fetched, what kinds are being indexed, and how long it is
taking.  I have noted from your previous posts that you seem to be indexing
a lot of very large EXE files.  This is useless and you should be excluding

(2) Please look in the manifoldcf.log file for evidence that fetches and/or
Solr indexing requests are being retried due to errors.  It doesn't take
many documents being chronically retried before forward progress drops to
near zero.

(3) If you look into (1) & (2) and everything seems fine, it may be a
misalignment between availability of several kinds of resources that is the
problem.  Please get a thread dump of the agents process while it is
crawling, using jstack.  Post that thread dump and we can tell you what to
look at next.
