Hi Eugene,


Thank you so much really!


As those values seem to be related to basically the average service time= in the disks and the average service times increases in crisis moments..= =2E I assume yes it does...


I will obviously keep an eye on them... sure...


Thanks again!

= We may have 600 deletes/sec at busy times (acording to what I see in gstat= and calculating when having two masters)....

As I've said, you need to monitor ALL values, there no unimportant o= nes on that screen.
Look also at ms/r, ms/w and ms/d - that is, milli= seconds per read operation, per write and per delete.
Do these times = grow at peak time?
