Summary0001259: Background pumping killing disks
DescriptionWhen using IBLMPump in background pumping mode, abnormal amount of IO operations are generated on disks where transaction log database is located.
When normally we have about 50 I/O operations per second (IOPS) on the disks with IBLMPump running there is around 30 000 I/O operations per seconds on the disks. As a result replication crashes.
Is there a way to tweak application so it won't kill disks?
