    Default XML Speed

    We are using a 62K XML doc to describe a series of questions that branch depending on the answer. It contains the text of the next question as well as the logic of the branching and displays via .ASP pages. The XML doc is Attribute heavy. Performance kinda sucks. As the questions get near to the end, a noticeable pause develops as we read through the tree lower and lower. The pause is about 100ms, not bad, but a noticeable refresh flicker. The server is 2 processer 550 Xeon and 1 gb ram, with 10 10k drives in a RAID 0+1 volume so we have the hardware. <BR><BR>Questions:<BR>Does anyone know how bad the performace will degrade as users hit this? I know it depends, we are using DOM and are thinking of trying the free threaded DOM... <BR><BR>Is performace this bad with MSMXL 3.0? We wanted the reusability and ease of maintenace with XML, but performace would definately have been a lot better with a script defined in SQL server. <BR><BR>Any suggestions on XMl performance? Attributes vs. Elements?

    &nbsp;<BR>From what I&#039ve read on MSDN and other places, the limit on XML files is about 50k. Check out this article for a little more info:<BR>http://msdn.microsoft.com/xml/articles/xml09182000.asp<BR><BR>Since your files are already attribute heavy (generally you can use attributes instead of child elements to reduce size), you may want to break them up into 2 or 3 different files.<BR><BR>HTH<BR>Richard
