Hi,

We have an index of approximately 400GB in size, indexing 5000 documents was 
taking 20 seconds. But lately, the indexing is taking very long, committing the 
same amount of document is taking 5-20 mins. 

On checking the logs I can see that their a frequent merges happening, which I 
am guessing is the reason for this, how can this be improved. My configurations 
are given below,

<useCompoundFile>false</useCompoundFile>
<mergeFactor>30</mergeFactor>
<ramBufferSizeMB>64</ramBufferSizeMB>

regards,
Ayush
