I have just tested on virtual machine, back-wt LDAP ADD(with single
thread) is 20-30x times faster than back-bdb.
I'm looking forward to benchmarking with many thread.
I'll publish benchmarks just when I get high spec machine.

WiredTiger is planning to implement RPC for multiprocess access.
http://source.wiredtiger.com/2.5.3/group__wt.html#ga9e6adae3fc6964ef837a62795c7840ed

I think it will communicate with unix domain socket.
I'm planning to use the feature to avoid multi process locking.

Thank you.
