When calculating render times/costs for upcomming projects i would love to have an information on how long a similar rendering took in the past. Would it be possible to save some sort of tasks report .txt together with the frames to the Output folder where i can see all the frames with the corresponding rendertimes and slaves?
Could you use the Farm Reports feature to look at statistics for previous rendered jobs? It’s available under the Tools menu in the Monitor while in super user mode. The documentation for it can be found in the PDF/CHM user manual you can download:

If that won’t work for you, you could probably create an event plugin to do this after the job completes. You could use the JobUtils.CalculateJobStatistics function (which takes a job and its corresponding task collection). This function returns a JobEntry object that has a bunch of statistical information about the job. You can find this function in the PDF/CHM scripting reference that you can download as well from the link above.
Cheers,
