The current wpad.dat look like this:

  function FindProxyForURL(url, host)
        if (!isResolvable(host) ||
            isPlainHostName(host) ||
            dnsDomainIs(host, ".intern"))
            return "DIRECT";
            return "PROXY webcache:3128; DIRECT";

The browser seem to become quicker by changing this to a simpler one:

  function FindProxyForURL(url, host)
        return "PROXY webcache:3128; DIRECT";

Can you test if this help for you too?  Replace the file
/etc/debian-edu/www/wpad.dat with this simpler one, and see if it work
as you want it to.  Is it a problem to use the proxy for everything,
also for non-resolvable addresses and for local addresses?
Happy hacking
