Yes, it will check them all, but since this is down.asp performance is not really an issue.
In topic.asp when request("ARCHIVE") is specified in the code and ARCHIVE=true does not exist as a querystring IIS will check all 5 collections. Thats a performance hit every time topic.asp is viewed. Servervariables is the most expensive to query cpuwise as IIS has to retrieve a lot of data to respond e.g. http_host, server_name, etc. If querying all 5 collections can be avoided I think it should be.< |

That is a fair point, and one I hadn't considered,it actually checks it twice if it doesn't equal true , now what would be interesting is to see what kind of difference it does make.< |

You would expect that because request("ARCHIVE") is used twice that it would "cost" twice as much but in truth it only costs slightly more. I read something somewhere a long time ago that stated that the second time you search the collection isn't as cpu intensive as the first.
I doubt I will be able to get conclusive proof that that line is to blame for IIS crapping out. In my view it could only have been a (small) contributing factor at most but at least I can eliminate it now. I'll update this thread if I find anything.
Thanks for your help, Huwr.< |
