Yes. > And, delay in transaction submission is expected in this case (causing > tps to bring down). Yes, delays caused by inter-sample processing would generally affect TPS only. > Sebb, can you please explain how the connection handling is different in > AB & Jmeter? Sorry, it was a long time ago that i used AB.

I suggest you try a comparison using 1 thread only. Also, make sure that JMeter runs for several loops, as there will be some startup overheads. I assume both AB and JMeter are running on the same host? > Warm regards, > Kaushal Kishore > > > -----Original Message----- > From: sebb [mailto:[EMAIL PROTECTED] > Sent: Friday, April 04, 2008 5:48 PM > To: JMeter Users List > Subject: Re: Difference in AB and JMeter Results. > > On 04/04/2008, Jae Joo <[EMAIL PROTECTED]> wrote: > > > > Yes, I have same experience.
