Unusually long time for geometry optimization

[Megha Anand]

Dear CP2K lovers,

Please help me figure out what I doing wrong. I am using GAPW method 
(non-periodic) to perform geometry optimization on an iron complex. The 
starting geometry for the CP2K job was taken from G03 output and it took 
~900 steps for the same geometry to converge. The final energy differs from 
G03 energy by almost 0.1a.u.

Since there could be so many variables in my input that could be 
contributing to the problem, I am lost as to where to start from. Experts 
please help me with your suggestions so that I can settle down with 
starting conditions for my system in this project. I took inputs from 
different discussions on this group to create the input but it does not 
seem to be working for my system. 

I have attached the input and output file. Thank you so much for your help 
and time - Megha
