On your questions below:
- I had 128MB RAM + 256MB swap file. Changed that to 200MB RAM + 256MB
swap. No performance improvement.
- Yes, X11 goes over TAP, SLiRP is disabled, I have a bridged (pcap)
connection for all the other routes then to the windows host.
- the hostname was not present in the /etc/hosts file, add that per your
comment, no performance improvement

Note once again: if I start xclock it starts within 0.5sec. If I start
gedit it can take 5 - 10 sec.

The real annoyance is with evolution, as switching from 1 mail folder to
another, or from mail to calendar can take 5 - 10 seconds. Worse, click
create a new e-mail button take 5 - 10 seconds for the new window to
appear.

It seems the problem is caused mainly on new window creations for/from a
gnome application.

My .conf file:
----

kernel=vmlinux
cobd0=images\rootfs.img
#cobd3=images\rootfs_.img
cofs0=config
cofs1=c:\
root=/dev/cobd0
ro
initrd=initrd.gz
mem=200
eth0=pcap-bridge,"LAN-verbinding",0A:C0:71:65:08:01
eth1=tuntap,"Pubuntu-TAP",0A:C0:71:65:08:00
exec0="C:\Program Files\Xming\Xming.exe :0 -notrayicon -ac -wm -clipboard -multiwindow -dpi 100 -xkblayout us -xkbmodel pc105"
exec1=pulseaudio-0.9.6\pulseaudio.exe

You should post your configuration (Windows side), so we can check it.

Check your free memory with "free" under Linux. Try to give more memory
to the coLinux with the config option "mem=..." (in Megabytes). Add a
swap file, if you have not enough memory.

Check your network configuration, that X11 truely goes over TAP-Win32
and not some wired ways over SLiRP and/or your local network. Disable
temporally your SLiRP or Bridged things, in the coLinux config on
Windows or by calling "ifconfig eth0 down" under Linux. Remove
temporally your network cable from Windows. Than check the performance
again. Or boot Windwos without network and check the launch speed.

Check your name resolution (DNS). Check, that the coLinux "hostname" is
listed in the file /etc/hosts with the ipaddress of tap on the Linux
side, and also with an other name and ip for the TAP-Win32 side. For
example:

  192.168.0.1   windows
  192.168.0.2   colinux

The real names for Windows does not matter, but you must use your ip
addresses there. Some programs tries to resolve back the ipaddress to a
hostname, and if you don't have a real DNS-Server for the TAP addresses,
this can be timeout you have seen.
