This ia with 6 concurrent data streams. In addition to the
/proc/sys/vm/dirty* values I also adjusted
values in mm/page-writeback.c eg. MAX_WRITEBACK_PAGES to 8192 . Our
goal is to blast out
as much as possible per pdflush invocation.
These are healthier numbers. How many disks are on that machine? What
raid level? Does it have battery backed up cache?
Anyway you need to check you network, since it looks like block
throughput is not the issue.
