Hello,
1. To increase the performance of webclient, You could increase the memory allocated to webclient.
2. In 6.0 you can still utilize VMware vSphere client to connect to vCenter server and perform most of the required actions.
3. From vCenter 6.5 vSphere client has been degraded.
4. Alternate way is to use the HTML version to connect to the vCenter server.
Steps to increase allocated memory to webclient.
1. Increase the memory allocated to vCenter virtual machine by 2GB.
2. Manually increase the Perm Gen value, by editing the service-layout.mfx file
3. Increase the amount of memory assigned to the services by running the command cloudvm-ram-size.
Steps to Manually increase the Perm Gen value
1. Take backup of service-layout.mfx found in location /etc/vmware. To take a backup use the command : cp service-layout.mfx service-layout.mfx.bak.
2. Stop vsphere-client service. [service-control --stop vsphere-client].
3. Open service-layout.mfx. by using the command vi service-layout.mfx.
4. Change MaxPermMB size from 256 to 512 or 1024 for the row vspherewebclientsvc.
5. Start vsphere-client service. [service-control --start vsphere-client]
Using command cloudvm-ram-size:
