Have you changed your firewall settings lately?��This�slowness�happened�to me once when, by mistake, I set the default policy in the iptables nat and mangle tables to DROP.��That�stopped�all�traffic�on�the�loopback�interface, which made my whole system (but especially KDE) slow to a crawl.��Took�me about a week to figure it out. You can check this easily. Run the following commands as root: # Allow all traffic to pass on the loopback interface iptables -A INPUT -i lo -j ACCEPT iptables -A OUTPUT -o lo -j ACCEPT # Set default ACCEPT policies on the nat and mangle tables iptables -t nat --policy PREROUTING ACCEPT iptables -t nat --policy POSTROUTING ACCEPT iptables -t nat --policy OUTPUT ACCEPT iptables -t mangle --policy PREROUTING ACCEPT iptables -t mangle --policy INPUT ACCEPT iptables -t mangle --policy FORWARD ACCEPT iptables -t mangle --policy OUTPUT ACCEPT iptables -t mangle --policy POSTROUTING ACCEPT Good luck, Andrew.
