Summary of Problems : Bad performance read /write | Snap mirror taking ages to complete | throughput is very low
We have been experincing bad read/write latency since the summer and we upgrade to 8.1.4 P9 in september which made the problem go away for four weeks. Types of problems Users can't write/read small documents such a 1mb word document or it takes upto 1min to open them. The problem seems to be our netapp02 controller which has high ping rates from controller 1 to controller 2 but when you ping anything else on the network you get sub 1ms from controller 2.
Snap mirror lag times are horrdenous please see screenshot.
Netapp can't find anything wrong with perfstats, we are thinking its a bug or our config is incorrect somewhere.
Please could you guys help me investigate
