Remote Utilities slowing down the host machine

I have Remote Utilities installed on a bunch of machines, and I really love it. Unfortunately, a problem has just come to my attention. Two of these machines, one is Windows 8 and one is Windows XP (I know, I know), have been causing problems for the users because of system slowdowns over the recent days and weeks.

On the Windows 8 machine, I found that Task Manager showed Remote Utilities host using 25% of the CPU, even when no one was connected. I stopped the host and the speed problems appeared to resolve.

I just tried stopping the host on the XP machine where the user was complaining of slow performance, and that seems to be resolved too.

On both machines I do have ESET Endpoint Security installed, and when Remote Utilities host was running ESET also seemed to be using up a fair amount of CPU as well. So it's possible that there is some interference there? But a Google search as well as an ESET forum search for Remote Utilities produces nothing, so I thought I would ask here in hopes that someone has some ideas for me.

Thanks in advance.

Hello Josh,

Thank you for your message.

Could you please try to add Remote Utilities rfusclient.exe and rutserv.exe files to ESET exceptions?
This article could help you with that.

Looking forward to your reply.

I'm facing the same slow-down, however, it's on servers (1-host & 3 guest VMs). It appears to happen when you start a session, or multi-session, and let it sit for a while with no activity. Once you return, it's very sluggish and a lot of the time it will appear to be frozen. If you want for 1-3 minutes you can watch it paint the screen, trying to "catch-up" with the user.

It appear as-if the link between the session times-out .vs. keeping it alive with a "ping" to each other. So when the user returns to the session, it try's to re-initiate the connection - creating the lag. Problem is, the sessions returns, but it's noticeably slower than the initial session.

Hello Michael,

Thank you for your message.

Could you please clarify what process exactly is taking resources? And do you have Screen Record feature activated?

Looking forward to your reply.

Hi Anton,

My normal use is starting up four sessions. I may be working in one for a while and then switch to the other. If I move the focus away from the screen and read my e-mail, browse the net, etc. and return back 10-20 minutes later, the session moves very slow or they sometimes just disconnect.

The Windows firewall is deactivated on all servers at the remote site, however, there is the normal corporate firewall. None of the servers have anti-virus software.

So, I'm note sure what function is causing the slowness as I'm only using the remote function and occasionally the transfer functions.

Could you please open Task Manager on the Viewer machine and on all Host machines and check, if our processes rutview.exe, rfusclient.exe and rutserv.exe use too much memory or CPU when the connection becomes slow?

Looking forward to your reply.
