Problems with interpreting "Historical Performance Trends"-report

-

hi all,

we installed performance reports published grant holliday, i'm not sure if unterstand them right way.
infact of using sql 2005 can't use reports, example "historical performance trends" report. tried show how time saved improving response time of version control request, calculation said, users spent 8 days while waiting response in last 2 weeks, sounds lot.
here calculation:

50 intervals in 2 weeks multiplied 22.673 requests per interval (average of total number of source control download requests chart) multiplied 600ms per request (average time of version control)
= 680.190 seconds
= 11336,5 minutes
= 188,94 hours
= 7,8 days

am missing or our users realy spent 8 days of waiting tfs?
are there references given ms compare with the average values have? (~20 team projects, ~200users, ~50gb of data in sql)
thanks far,

michael

hi michael,

if you'd send me copy (granth @ microsoft.com) of rendered report you're concerned about, can have @ it.

you might interested in tfs performance heat map report created before joined microsoft. give clearer picture of specific version control commands.
