F5 icontrolsnapin new version required. Very slow in data import

Hi all,

 

I am using F5 icontrolsnapin 11.0.0.2 version to get the data from F5 GTM & LTM. Recently our environment upgraded to F5 GTM & LTM12.1 version. After upgraded to 12.1, now I am getting very slow data import through icontrolsnapin module. Do we have any latest version of icontrolsnapin for 12.1. Only 11.0 installation files are available. Please share what I need to update to get the data imported faster.
