The pysphere API is no longer used when monitoring ESX vCenter systems. We are now using much simpler tools to evaluate the vCenter response instead, thus saving quite a lot of cpu time. Depending on the number of ESX Hosts and virtualmachines you will see a performance increase by a factor of 40-200.

Note:
If the "Compatibility mode" is set in WATO the old "pysphere" version is still being used. This option remains for older (<5.0) ESX versions.
