Large customer - vCenter 5.5 U1c Web Client Response Time/ Performance and Navigation issues

Jump to solution

So we all are aware of the issues with vCenter 5.5U1 web client and how we are forced to use it to make use of any features of vHardware v10, vDS 5.5 (switch config changes sync issues if an emergency change is made on c# client vDS) VSAN only available through web client, flash issues, sluggish to not responsive issues, and the list goes on with the layout of menus and hard to navigate, SSO issues (still after 5.5 enhancements)

So is the vCenter Architecture team @ VMware going to make an effort to hear and act upon the much needed performance enhancements and UI enhancements before adding on more features and SSO type services which majority of the customers don't use, and not force it's customers to continue to loose faith in its vCenter product?

Looking for some answers with options to strip vCenter 5.5 U1c installation down along with a promise to address these in vCenter 6.0 release!

Here is your answer. First, use Chrome as browser, second you need to go with atleast 4vCPU*32GB of RAM & adjust the java heap sizes for SSO, Tomcat management server (TC), inventory server and Profile driven storage to "fine tune" vCenter appliance with embedded or external Oracle DB. I did this and performance gains went 10X. This includes running vSAN enabled clusters. My recommendation that works great based on design documents:

vCenter Server Inventory

VMware VirtualCenter Management Webservices (tc Server)

Inventory Service

Profile-Driven Storage Service (sps)

Large inventory (More than 400 hosts or 4000 virtual machines)

  4GB

  12GB

  4GB

Memory tuning on vCenter server appliance 5.5

  • Log in to vCenter server appliance using SSH
  • vi /usr/lib/vmware-vsphere-client/server/wrapper/conf/wrapper.conf configuration file, look for JVM memory section and change maxmemory to 4096
Line 66##############  JVM Memory#############wrapper.java.initmemory=512wrapper.java.maxmemory=4096
  • vi /usr/lib/vmware-vpx/inventoryservice/wrapper/conf/wrapper.conf configuration file, find wrapper.java.maxmemory parameter and change it to 12288
Line 116# Maximum Java Heap Size (in MB)wrapper.java.maxmemory=12288
  • vi /usr/lib/vmware-vpx/sps/wrapper/conf/wrapper.conf find wrapper.java.maxmemory parameter and change it from 1024 to 4096
Line 154# Maximum Java Heap Size (in MB)wrapper.java.maxmemory=4096
  • Reboot vCenter Appliance w/ external DB(1000 hosts)/embedded for lab (100 Hosts)

PS: vCenter 6.0 has much better performance based on my beta testing .. so don't loose hope yet. Lots of enhancements coming ...

PS: I also vented about this here until I figured this out just recently: Re: Large customer - vCenter 5.5 U1c Web Client Response Time/ Performance and Navigation issues
