SVE performance

Now we are using about 100 share varible and still all in office LAN, but takes 3 or 5 mins to initial the share varible link, any setting can improve it?

Hi turbot,

What exactly to you mean by "initial the share varible link"?  Do you mean deploying the shared variables?  Are the shared variables bound to any data items?  We need a little more information to find out what's going on.

The 'initial' means the PSP LED turning from red to green.

They have already been deployed from server side.

They are binding to some data from OPC server, but the data is already available.

turbot,

It really shouldn't take this long.  Can you replicate this behavior outside of LabVIEW?  For example, can you undeploy and then redeploy your library.  After redeploying can you immediately get a value from the shared variable manager (Tools->Shared Variable->Variable Manager)?

I  have tried undeploy and deploy, it still took 5 mins to initial the link, any where can debug it?

[Justin D]

Have you tried using the Shared Variable Manager like I mentioned in my last post?  This would be a good debugging step to take LabVIEW out of the equation.

-Justin D

[alex.]

Yes, I tried, but still the same.

[Justin D]

Please clarify what happened when you tested this using the shared variable manager.  After deploying your variables does it take 3-5 minutes for the shared variable manager to report the value of the variable?

[alex.]

Yes, in the share variable manager, it will take 5 mins to see the quality turn from 'connecting, disconnect' to 'good' after deploy.

But in client side, it will still take 5 min to connect, even if I have connected already and closed the vi and re-open it.
