Synergy choppy cursor at times on client


I use a program called Synergy so I can have 3 monitors using a secondary PC as Linux multi monitor support is lacking beyond 2 monitors so I have my main machine which has 1 monitor and a lower end secondary machine to run the two other monitors. I can then display stuff on the other screen by opening the right app on the secondary PC by simply moving my mouse over, as if it was a normal multi monitor setup.

One thing that is very irritating is that if there's any kind of javascript on a web page, such as in phpmyadmin, the cursor is extremely hard to move, it just gets really choppy and slow, even typing is choppy. Completely unusable. Is there a way to fix this?

They don't seem to have a forum or much on their site unfortunately. Is this app even still well known? Is there a better way to accomplish what I need, which is to control a secondary PC with the same keyboard and mouse without needing a KVM? (those are slow to switch over, I need to be able to go back and forth instantly by moving cursor across screens) My main PC is also in the middle, the other has a two monitors, one on each side. In synergy I was able to configure it so it works properly that way, basically the second machine is a dual monitor setup where the screens are inversed with the main one in the middle.

Synergy is still the only app I could find which would do this. You're right that there isn't much support. I ended up making a donation and then using that to write to one of the programmers directly. It took about 2 weeks to get a response even then.

Check the client system when the javascript is running. Is CPU or memory being spiked? The only other thing that would really affect this would be network traffic, which seems more unlikely unless those specific scripts are causing all sorts of traffic on the network.

I can confirm the cpu is being spiked during the times where it gets choppy, but this is a dual core processor, this should not really matter, but for some reason it seems to still do. Is there a way I can dedicate a core to that app or something?

You could renice the synergy client app so it has greater priority. (You should probably also lower the priority of whatever is spiking your CPU.) Programs don't evenly distribute among multi-core systems. I would make more sense to have both processors running at 50% instead of one at 100% and one at 0% but right now the technology just isn't there. (We basically need better multi-core process threading.)

Give that a shot and see what happens.

What you are looking for is 'processor affinity' using 'taskset.'

Do a search and pick the article regarding your loadout.
