Slow performance to read/write shared variables programatically

[MMCDAT]

We are using datasocket read and write functions to read and write shared variables programatically (in the same machine) but we only achieve a performance of aprox. 200 reads/writes per second. We are using Labview 8.6 with DSC.

Is possible to get better results? That performance is normal?

Any help would be appreciated. Thank you in advance.

Hi MMCDAT,

I think this value can be normal as you can see in this link:

As you can see, the limit for datasocket depends on your Ethernet limitations, even if you as using it just in one PC:

You can improve the performance changing the update mode or Vis configurations:
