Virtualization, VMware ESX
How long has it been since you have taken a look at the VMware Virtual Infrastructure 3 (VI3) SDK? A month? Two months? Six? Maybe you were originally turned off by the SDK because of its hard-to-use traversal mechanism, or maybe you could never get your application to take less than a good minute to connect to the VI3 SDK web service. If your bad experience was because of the latter, you are in luck. Earlier this fall VMware released a patch for there VimApi namespace that changes the way that the serialization code is generated. The KB article that resolves this issue is located at VimApi.
I myself have tried solution #1 and found it to rapidly speed the connection times up. However, truthfully, the process of querying or setting data via the VI3 SDK is still slow. Hopefull VMware is working on this issue and a solution will make it into future releases of ESX.
Hope this helps!
