If your a commonwealth bank customer and you use ubuntu or other linux OS you may find that the Netbank website is extremely slow to login to.
Solution install nscd name server cache daemon
sudo apt-get install nscd
by the way this was found out by putting a complaint into the commonwealth bank which the complaint was swiftly replied to with generic flush your DNS for windows instructions and further instructions saying that AVG link scanner also is known to slow down Netbank. but once I dismissed these solutions as not solving the problem they then actually asked real questions got me to try and different dns server. I also got plenty of phone calls check that my problem has been resolved or that at least someone is attempting to fix it so there ads must be right..
In the long run Commonwealth bank need to fix there DNS so that there sub-domain address is faster to look up.
In the short term my problem is fixed if it’s only a speed increase when I log into Netbank for the 2nd time, since the cache seems to clear on each restart.
