Re: Wait LCP to ensure durability

Hi Mikael,

looking at the ps -eLF output it clearly shows that the io threat is only executed on CPU#11. There is no other process using that CPU.

This is the CPU where we have 0% idle. It seems we are performance-wise CPU bound there.

Is there anything we can do to improve that? Maybe reduce/increase Parameter DiskIoThreadPool (currently 8)?
