VM slow for first response after some time idle
If you use the virtual appliance version of Searchdaimon ES, it can also be caused by VMware. Some times this only happens the first time you search. If this is the case, then most proboly the ES's memory is beeing swaped out by the hypervisor. Try setting a memory reservation for the virtual appliance to avoid this from happening
Performance can be improved by removing other virtual machines from VMware, or by installing more memory on the VMware server. A hardware installation of Searchdaimon ES doesn't have these issues.
It take a long time to login to see the search box. Then Search is fast
When you log on you are prompted for username and password. ES verifies thus credentials with your user system (Active Directory or other ldap system). ES also need to get witch group a user is member of. If your user system is slow to respond, login can take some time.
