Thanks for checking. The patch didn't make any significant difference. 
Now its 1.3G instead of 1.5G.

root at server:~# ls -lh /home/admin/mails/lucene-indexes
total 1.3G
-rw------- 1 nobody nogroup 1.3G Aug 18 11:30 _4a.cfs
-rw------- 1 nobody nogroup   20 Aug 18 11:30 segments.gen
-rw------- 1 nobody nogroup   46 Aug 18 11:30 segments_8n
