Slow time to load policy asm

Hello team,

as I mention in the lasty mail that I have sent, doing a deep inspection I have verified that the problem is referred to an excessive use of cpu, in a short the values are beetwen 95%-98%. The version that I'm using is 15.1.5. I have identified this problem by using F5 V.E. and phisical device ( bigip i2600 ). F5 portal suggest to improve the version but, If i have being honest, I have the some problem by using 16.xx and 17.xx version. At the moment the problem is verified on the device that has not processed traffic, the module installed are:

ltm and asm.

Someone could help me to fix it ?

Many yhanls in advances.

Rgds,
