Bandwidth use ?

[kinuris]

Hello,

I'd like to know how much traffic UltraVNC generates. This is because I will have to use a wireless pay-per-Mb connection next month.

The scenario will be: two WinXP machines, 1024*768, a windows database application (adding and browsing data, maximized).

I think it is not easy, but you help me a lot only trying to make an approach.

Anyone could estimate how much traffic I will gererate ?

Thank you in advance.

Here I go again !

Yes, I know it is not easy , but any help will be welcomed

Please....

Estimating bytes transferred in a VNC session:

While I haven't done it myself, there are various programs which will measure data transfer speeds. I would expect to find a free program fairly easily. Then simply use VNC for a while and see how many bytes have been transferred.

A Google search finds the following (which I have not downloaded myself).

OK. I thougth it would be some estimations. Anyway, it is a good solution.

Thank you.

> OK. I thougth it would be some estimations. Anyway, it is a good solution.

I don't know if a generic estimate is possible -- it can depend upon the screen resolution and nuimber of colours, the speed of your connection (which might affect U;ltraVNC's encoding), whether you are using fuuzy screen, using or not the NT/2000/XP video driver, etc.

With byte-logging you can see the effect of different options and minimise the data transferred consistent with a usable picture.

Maybe you could reduce data transfer by working with one window instead of the whole screen? Maybe not, if the rest of the screen is not changing?

My pleasure.
