Hemant Tiwari commented on JENA-2204:
-------------------------------------

Thank you Andy for help.

_"Show the directory listing with sizes." :_  I have attached my TDB2 index 
data with LUBM dataset.

Jena Index :
--------------------------
Jena Version : 4.0.0
JVM : 64 Bit
Triple Count : 100k 
Original Size : 150MB
Size after Compact : 140 MB  
Size after Zipping : 1.5 MB  
--------------------------

How can I go 5x to 10x lower on storage consumption ? 

> Storage required by TDB2 is much higher than TDB1, How to Fix ?

> The storage required by TDB2 is much higher than TDB1
> For 100k statements - TDB1 takes about 90 MB, while TDB2 is taking ~ close to 
> 1 GB.
> Why is there such a difference and is there any solution available to reduce 
> the storage size?
