Yes it is this checkbox :) I've tried without retrieving images; it seems more stable but i have always many bad response time, like a serie of ~150ms and some ~30ms; finally it gives an awful graph with many uncoherent responses :/ i don't know what to do... > > -----Original Message----- > From: Jeremie Blanc [mailto:[EMAIL PROTECTED]] > Sent: Monday, May 13, 2002 9:53 AM > To: Stover, Michael > Cc: 'JMeter Users List' > Subject: Re: not coherent response time > > > Stover, Michael wrote: > >>Unless you've verified with other sources that the times are in reality >> > more > >>constant than what JMeter reports, I'd be inclined to trust what JMeter is >>telling you about your site. >> >>I've hit static web pages with JMeter, and I've hit databases with JMeter, >>and often gotten results with a near-zero standard deviation (ie, very >>consistent).
