I've found the biggest kicks in performance is HIGH RES WALLPAPERS! They eat up som much bandwidth because VNC has to send all that data across to the viewer. I've set all my server to the plain jane blue to keep speed up.
One other thing I noticed slowing it down is resolution. 800x600 on a local lan works great, just like I was sitting in front of the machine, but any higher even on a local lan you'll see a perfomance loss. Over Cable modem it would become unworkable when you start going over 800x600. -----Original Message----- From: Mick [mailto:[EMAIL PROTECTED]] Sent: Friday, February 01, 2002 10:35 AM To: [EMAIL PROTECTED] Subject: Win 98/95 setup - slow access Hi, I'm trying to set up a VNC connection to support a friends computers and network. I currently have one of his machines at my house re-installing a broken Win95 system but want to be able to connect to him once I've taken the machine back. I've set up the server on his machine and the viewer on mine and tested it on my LAN but it seems to work awfully slowly compared to normal network access to his machine. I'm concerned that trying to support him over the net might be unworkable, even over a cable modem. I originally set up the server in "App Mode" rather than as a service so that he can choose when to turn it on and relieve the system load/security issues when he doesn't need it. I then tried it in service mode but didn't notice a significant improvement. I can access his machine for file sharing etc. on the LAN through the Network Neighbourhood using Windows Commander and access is immediate, on VNC it's _painfully_ slow! The connection seems to be marginally faster if I change the connection options to "Raw" and "Full screen" but it's still orders of magnitude slower than normal network access so I figure I must be doing something wrong ;-) Questions I can think of so far: 1. Should access be faster in "Service Mode"? I can run him through the setup/removal if necessary 2. Does the difference in screen size put a significant hit on the video redrawing on my end? It does seem somewhat faster in full screen but still way behind network access. 3. Are there any other options I should choose/change? e.g. the Update Handling checkboxes 4. On this network, and on his, I'm also running IPX/SPX for File & Print Sharing/Netbios/Gaming access. Does this negatively affect VNC? 5. Am I just underpowered? - See system details below Any pointers gratefully received. I'm hoping to get his machine back to him and set this up tomorrow - Saturday Thanks, Mick System Details =========== VNC Version - Windows32 v3.3.3r9 on all machines.
