I'm using 13.10 stock, so Unity.  I'll have to catch it again to see how 
much MB it's using of RAM, but it bogs the whole system down to a crawl.  
Mostly reads, but some writes.

I have 2GB RAM, DDR2:

thufir at dur:~$ free -h
             total       used       free     shared    buffers     cached
Mem:          2.0G       1.6G       320M       174M        55M       884M


but this is when everything is fine.  


thanks,
