I've been running on a laptop in a remote obs and noticed that when I login remotely via VNC software, Maxim consumes nearly 100% of the CPU? I think this has been a problem since I've started using Maxim, has anyone else experienced this?

This topic comes up every few months. I too use UltraVNC to monitor MaxIm activity from my Ipod Touch. But for remote operations from a real computer I use Remote Administrator. UltraVNC is quite slow in comparison, but it does work. I've not checked CPU utilization, just watched how often the screen is updated. I tried Microsoft's remote stuff in XP a few years ago and vastly preferred Remote Administrator. Although Microsoft may have improved it with Win7.

On Linux rdesktop lets you pick the screen resolution, this can save a

lot of CPU I expect.

If you can handle Linux that might be the way to go.

I turn off windows updates and do them manually.

I've been caught 3 times trying to shutdown the computer because of

approaching thunderstorms only to discover it wants to finish an update.

Thanks for the link Mark, and the reply Lawrence. This AutoReboot feature was the tipping point for Norton, as far as I was concerned. I don't understand Software writers that feel their patch is more important than the work you are attempting to complete on the Computer. It seems like since MicroSoft announce the end of support for WindowsXP, they have been issuing major updates at a pace of at least one per week. AlanP



BTW, it is my understanding that the Home version lacks remote support. But as TightVNC has worked so well for me, I would be reluctant to change at this point.

I have used UltraVNC for years and am generally quite pleased with it, but I am actually a pretty big fan of Remote Desktop. I know everyone has their own favorite, but given the choice now, I think I prefer RDP over the VNCs... However, if what you are using is working well, them I agree you should not change.



I will send you a link offline that may be a little food for thought.



Agreed about the updates though. It is absolutely maddening.

Thanks for the many suggestions. It would seem that this isn't something experienced by many, if any, users. I run XP home on both PC's, don't care to monkey with Linux. I've monitored the VNC CPU usage and it generally runs around 10-15%. Maxim consumes the rest, but ONLY if a remote terminal has been established. I have VNC running all the time on the host in the obs...it's only when the remote session is enabled that the CPU usage goes through the roof. Without the session, Maxim is around 5% (more obviously during downloads et.al). I just can't understand how the two apps are even related and why maxim freaks when a remote session begins. BTW, no other programs have this issue.

You need XP Pro in the observatory computer to support Remote Desktop.

XP Home will work fine at the other end.

I've stayed away from all the Home versions of windows so I can't tell you if it is supported or not. I imagine it is... for support. Maybe another forum can direct you on how to do it with Home. The difference between the RDP protocol and most of the other remote tools is the way that the data is transferred, which might explain why your CPU usage is so high. With VNC, TightVNC, etc, those utilities are what's known as "screen-scrapers". They monitor the vidoe buffer for changes (usually in small tiled areas) and transmit the bitmap of the part of the screen that has changed. If there is a lot going on, like blinking stuff, guiding graphs, the guider window, etc., it will chew up both network bandwidth and CPU. With the RDP protocol, only the commands that are being sent to the graphic device layer of windows are sent to the remote machine and they are played/re-executed on that local machine. Thus, mouse movements, moving windows, text, etc., all seem about as fast as they would if you were sitting at the computer.

However, if you have Task Manager up and monitoring CPU performance, you can move task manager so that everything but the CPU percentage number is off the screen or covered by another program. That will stop the transmission of the graphics. If that test doesn't change the performance, it isn't your problem and you can stick with VNC and try to figure out what else the problem could be.
