Opmanager and Servicedesk plus

Opmanager and Servicedesk plus

I have both Opmanager 9.0 and Servicedesk plus 8.1 installed on the same machine.
It seems that after I upgrade to servicedesk 8.1, the whole system is very slow.
 
Is it advisable to have both on the same server.
 
the machine running the application is not very high end.
just a windows 7 professional desktop.
