yeah.. i thought so that it should not effect in 4000 documents.

I am using filesystem connector to crawl all of my C drive and output connection is null.

There are no error logs in MCF. MCF is standstill at same screen since half an hour.

Attaching some snapshots for your reference.

Hi Ameya,

4000 documents is nothing at all.  We have load tests which I run on every release that include more than 100000 documents on a crawl.

Can you be more specific about the case that you say "hung up"?  Specifically:

(1) What kind of crawl is this?  SharePoint?  Web?
(2) Are there any errors in the manifoldcf log?

Hi Karl,

I spent some time going through PostgreSQL 9.3 manual.
I configured PostgreSQL for MCF and saw the significant change in performance time.

I ran it yesterday for some 4000 documents. When i started running again today, the performance was very poor and after 200 documents, it hung up.

Is it because of periodic maintenance it needs?  Also, i would want to know where and how exactly VACUUM FULL command needs to be used?

It is fine; I am running Postgresql 9.3 here.

is PostgreySQL 9.3 version good because i already have it in my machine.. Though documentation says "ManifoldCF has been tested against version 8.3.7, 8.4.5 and 9.1 of PostgreSQL. "

If you haven't configured MCF to use PostgreSQL, then you are using Derby, which is not recommended for production use.

Instructions on how to set up MCF to use PostgreSQL are available on the MCF site on the how-to-build-and-deploy page.  Configuring PostgreSQL for millions or tens of millions of documents will require someone to learn about PostgreSQL and how to administer it.  The how-to-build-and-deploy page provides some (old) guidelines and hints, but if I were you I'd read the postgresql manual for the version you install.

Ooh ok.

Actually i have never configured PostgreySQL yet. i am simply using binary distribution of MCF to configure file system connectors to connect to Solr.

Do i need to configure PostgreySQL?? How can i proceed from here to check performance measurements?

Yes.  Also have a look at the how-to-build-and-deploy page for hints on how to configure PostgreSQL for maximum performance.

ManifoldCF's performance is almost entirely based on the database.  If you are using PostgreSQL, which is the fastest ManifoldCF choice, you should be able to see in the logs when queries take a long time, or when indexes are automatically rebuilt.  Could you provide any information as to what your overall system setup looks like?

Hi Ameya,

Have you read the performance page?

I have millions of documents to crawl and send them to Solr.

But when i run it for thousands documents, it takes too much time for it or sometimes it even hangs up.

So what could be the way to reduce the performance time? 

Also, i do not need content of the documents, i just need metadata, so can i skip content part from reading and fetching and will that improve performance time?
