New version .8 installed Windows 10

setgenerate true 50 CPU load about 50%

In the meantime I solved a block... so I have the following after block solve

If gen=1 and genproclimit=40 and minersleep =0 in conf Then Wallet freeze (not responsive) - CPU load  about 0-1%

if gen=1 and genproclimit=8 and minersleep =0  in conf then Wallet freeze (not responsive) - CPU load about 0-1%

if gen=1 and genproclimit=8 and minersleep =5  in conf then Wallet freeze (very slow response) - CPU load  about 0-1%

if gen=1 and genproclimit=4 and minersleep =0  in conf then Wallet freeze (slow response) - CPU load  about 0-1%

if gen=1 and genproclimit=3 and minersleep =0  in conf then Wallet freeze (a little slow response) - CPU load  about 0-1%
