Description

People notice slow rendering on german wikipedia.
The 702 formula heavy article https://de.wikipedia.org/wiki/Quaternion took 90 seconds for action purge. This is still good in comparsion the PNG rendering (7 minutes after clearing the math table in the database)
With rendering all formulae in parallel the execution time decreased to 15 seconds on the same machine. However, this might disturb the execution order for extension order of the tag expansion.
Moreover I think there is tuning potential in \VirtualRESTServiceClient::runMulti. I could not find any test / usages of this method.
