Re: [WebDNA] WebDNA slow processing

texte = I too am getting slammed. WebDNA regularly jumps to 99% and eventually becomes non-responsive. I'm on version 6.x on RedHat. I've been reviewing the .debug file. There are some columns that have data and I'm unsure what the information reflects. It'd sure be great if one of them was response time so I could spot problems, but basically I see lots of search engines pulling the same template with different parameters. Is anyone willing to share a pre-parse and post-parse script combination that would allow me to track response times easily? This could help find the problem/processor consuming requests. Can someone tell me what the columns in the debug file represent, particularly the mysterious numbers and blank fields? For columns, I see date, time, one mysterious number, a second mysterious number, an IP address, a consistently blank column, a template file path, user-agent string, three more consistently blank columns, the document name, the documentroot (or site home directory), URL parameters (everything after the ? in the URL), a blank column, a request header. It's hard to find a problem except that there've been so many requests. Thanks, Bill On Fri, Nov 25, 2011 at 9:53 AM, Thierry Almy
