Bob Dionne commented on COUCHDB-477:
------------------------------------

I tested this all against a clean checkout of trunk and it looks good. The new 
algorithm is faster on inserts[1] but interestingly for single inserts is makes 
for a larger db pre-compact. After compaction the db is smaller by a factor of 3

I thought we leave the new "sequentially random" as the default? Paul, is the 
concern just what's advertised to users?

Algorithms based on the system clock I think can be problematic as they assume 
all machines have the correct time.
