Comment (by bibilthaysose):

 I forgot to mention that I have been able to run some of the workloads
 (most notably workloada), and the performance for write operations is many
 orders of magnitude worse for Tahoe LAFS than for MongoDB.  Mongo writes
 about 11,000 entries/sec (on my thinkpad T50) and my Tahoe LAFS test grid
 (1:1:1) writes about 0.5 (that's one entry every two seconds) or so.  I'm
 not sure if that number would go up or down if I increased N/H/K.  I'll
 post the real numbers when I have them handy, but it hasn't been a
 priority because there are other workloads that don't seem to be running
 properly.  I want to make sure that the code is relatively bug-free before
 I actually post the numbers.
