A page Solr Performance Factors mentions 2 big tips that may help you, but 
you have to read the rest of the page to make sure you understand the 
caveats there.

In general, adding many documents per update request is faster than one per 
update request.  

Reducing the frequency of automatic commits or disabling them entirely may 
speed indexing.

Subject: Solr is working very slow after certain time   
Hi,

i could index around 100000 documents in couple of hours. But after that
the time for indexing very large (around just 15-20 documents per minute).

i have taken care of garbage collection.

i am passing below parameters to Solr:
-Xms6144m -Xmx6144m -XX:MaxPermSize=128m -XX:+UseConcMarkSweepGC
-XX:ConcGCThreads=6 -XX:ParallelGCThreads=6
-XX:CMSInitiatingOccupancyFraction=70 -XX:NewRatio=3
-XX:MaxTenuringThreshold=8 -XX:+CMSParallelRemarkEnabled
-XX:+UseCompressedOops -XX:+ParallelRefProcEnabled -XX:+UseLargePages
-XX:+AggressiveOpts -XX:-UseGCOverheadLimit

Can anyone help to solve this problem?

Thanks,
Ameya
