How to improve the performance when open big data file

[alex.]

The memory of the new PC is 2G.

The thing is after open on new PC, when I do zoom in/out, it is quite slow.

But I need to do more complex signal processing, this is what I worried about.

Any suggestion to improve it, thanks.

Zoom what in and out?

Nothing in your VI's have anything dealing with zoom functions.

Hmmmm...

now i know where that 11M data is going ...Directly to a graph or chrat...And zooming will defeneltly going to slow down

Is it really necessary to show all the 11M data on the graph?

Yes, the user may need to search and mark on the data, then start data processing.

Hi alex,

I get that the visualization of your 11M of data is the slow process.

And you do it just for the user to look at the data, so couldn't you just skip every second point or something like that to reduce the amount of visualized data? The User cannot distinguish 5.5M from 11M anyway.

For the processing you use the real 11M data of course.

Hope that this is a promising Idea 😄

Cheers,
