Hi there,
I suppose we cannot determine the value which will be expressed in KB/s or in MB/s
Performance history is stored for up to one year, with diminishing granularity. For the most recent hour, measurements are available every ten seconds. Thereafter, they are intelligently merged (by averaging or summing, as appropriate) into less granular series that span more time. For the most recent day, measurements are available every five minutes; for the most recent week, every fifteen minutes; and so on.
