Regarding the speed issue, have you modified the default 
CHUNKS_WRITE_REP_LIMIT and CHUNKS_READ_REP_LIMIT in mfsmaster.cfg?  
Following suggestions on the list, I have mine permanently set to:
     CHUNKS_WRITE_REP_LIMIT = 5
     CHUNKS_READ_REP_LIMIT = 15
instead of the default:
     CHUNKS_WRITE_REP_LIMIT = 1
     CHUNKS_READ_REP_LIMIT = 5
