Diagnosing slow deployment of templates or clones from vCenter Server
Symptoms
-
Slow deployment of templates from within vCenter Server
-
Slow deployment of clone in vCenter Server
-
You are experiencing high CPU utilization on the ESX host
-
You are experiencing high memory utilization on the ESX host
-
Slow response when administering an ESX host
-
Slow performance when copying files between shared VMFS storage (fibre-channel SAN) and local VMFS storage
Purpose
Resolution
Please validate that each
troubleshooting step below is true for your environment. Each
step will provide instructions or a link to a document, in order to
eliminate possible causes and take corrective action as necessary.
The steps are ordered in the most appropriate sequence to isolate
the issue and identify the proper resolution. Please do not skip a
step.
-
Verify if the slow deployment is specific to one template or if it affects all templates. To properly test this,VMware recommends to create a brand new template and test the deployment. This provides a clean test of the environment. For more information if template deployment is slow for a single template, see Deploying a single template is slow (1004028).
-
Verify that no processes are over utilizing the resources on the ESX service console. For more information, see Checking for resource starvation of the ESX Service Console (1003496).
-
Verify that the network configuration on the ESX host is optimized for the best performance, including speed and duplex settings. For more information, see Configuring the speed and duplex of an ESX/ESXi host network adapter (1004089).
-
Verify that the firmware on the RAID controller or HBA is up to date. For more information, see Slow performance caused by out of date firmware on a RAID controller or HBA (1006696).
-
Verify that the local storage or SAN array is configured correctly. For more information, see Slow performance caused by misconfigured local storage or SAN array (1006602).
-
Verify on ESX/ESXi 4.1 if the storage array devices in the environment support the hardware acceleration functionality and if they are responding correctly to VAAI primitives. If there is no VAAI support on the array cloning or Storage vMotion may fail at 18%. For more information see Cloning or Storage vMotion fails at 18% with the error: Failed to clone: Connection timed out (1029244).For further information on VAAI, see:
