Hi,

On the same physical server :
Domain-0, LVM2, 128MB memory
OLTP test statistics:
 queries performed:
 read: 140070
 write: 40012
 other: 20005
 total: 200087
 transactions: 10000 (111.09 per sec.)
 deadlocks: 5 (0.06 per sec.)
 read/write requests: 180082 (2000.53 per sec.)
 other operations: 20005 (222.24 per sec.)
Domain-1, LVM2, 128MB memory
OLTP test statistics:

 deadlocks: 5 (0.04 per sec.)
 read/write requests: 180082 (1422.30 per sec.)

Domain-1, GNBD, 128MB memory
OLTP test statistics:
 queries performed:
 read: 140000
 write: 40000
 other: 20000
 total: 200000
 transactions: 10000 (41.98 per sec.)
 deadlocks: 0 (0.00 per sec.)
 read/write requests: 180000 (755.68 per sec.)
 other operations: 20000 (83.96 per sec.)
I understand the fact that GNBD is slower than LVM2, but is Dom-U supposed
to be that much slower compared to Dom-0?
Regards,
Fajar
