Is this normal disk space usage for Fisheye/Crucible?

Question

My integrated Fisheye/Crucible instance is taking a significant amount of disk space:

prmpt:user[]du -h -s *

1K   backup

4.3G   cache

11K   config.xml

3.1M   lib

6.0G   var

prmpt:user[]cd var

prmpt:user[]du -h -s *

5.3G   cache

376M   data

0K   fisheye.lck

4.4M   log

28M   plugins

307M   tmp

The project's code base size is 143 MB with 13,758 files and 3,332 folders.
We started indexing at revision 13,806 and are currently up to 30,028.  We are not indexing tags, only trunk and branches.  I estimate about 60 branches have been created thus-far.
Fisheye/Crucible 2.5.1 is running on a Solaris box, backed by Oracle.
Is this normal disk space usage or does something look off?  
Thanks!

Compared to my fisheye instance your's is small :-) The cache vary in size depending on the amount of files commited per revision. One more variable are the branches (Wether or not the whole trunk is being branched).

One of my projects is very similar to yours and get's changed quite often. This single project comsumes 20G cache alone with about 28.000 revisions indexed and having 230MB in the trunk. 
In total my cache size is 120G.
