I am testing with AF 18.104.22.16822 using SQLExpress. What would cause AFElement.FindElementsByAttribute to take so long that I get an exception because the AFServer did not respond withing 5 minutes. I have tried setting the AFCache.CacheTime = 0 before issuing the request and it did not have any affect. I am starting the search at the root of my heirarch, but I do not have any large collections.
It appears that the SQLserver is using most of the CPU during this call.
