Bad performance with BlockIO

[Raudi]

O.K.

I used the DSS Demo CD and the performance is the same. Sequential read with one worker is fast and with two workers the value goes down after a few seconds.

I have asked engineers to review this issue - they may need logs from the DSS using your ticket # from last communications.

FYI: Engineers have confirmed that fileIO can by much faster in random access.

OK, so in my Enviroment there is in the current version FileIO the better choice.

Will there be changes in the future that more cache will be used in BlockIO? (When i'm right that the cachig in FileIO results the more performance in random IO.)

Our Research department will review this but they will need to time to schedule testing.

Hi Todd,

did you hear something?

This is going to take time for them to work on this as there are many projects in front that they have to complete first. Nothing I can do now.
