PLC DataSockets Speed

The VI i have developed has myriad data that it reads from an ALLEN-BRADLEY SLC5/04, the problem that i face is that the sheer load of data slows the pace to a crawling pace. what is supposed to be in real time is delayed by about 5-6 seconds.
I have reduced the time for update for certain addresses that need not be updated all the time, the others are at 100ms. i'm using LabView 7.0
I tried making SUB VI's out of these and using them, but this resulted in errors...the values read were pushed to other displays.

I hope i was clear...
any form of help or assistance is welcome,
cheers,
-U

As I suppose you are using Datasocket, then:
Put each Datasocked Read item in separate While Loop with Wait function not less than 100ms.
Do not read more variables then 30.
Do you need more - LabvieW DSC is a solution.
