WebDAV performance measurement

Hoping this is the right category.

Like other users I am not yet confident that the WebDAV speed meets our requirements. Before adjusting stuff I’d like to be able to measure impact.

Therefor, I found tools that seem to be tailored to owncloud and have very sparse instructions, like
https://github.com/individual-it/owncloud-performance-test and https://github.com/owncloud/administration/tree/master/performance-tests .

Do I miss something? Is there instructions somewhere how to reliably measure (specifically) WebDAV performance? Any hints on how to use which tools, which pitfalls to avoid (like cache warming, network latencies, …)?
