Is Ramp-up time in Jmeter affects concurrency ? I have 100 Threads in thread group and Ramp up time as 20. Will these 100 threads concurrent if ramp-up time is 20 Seconds?
As per theory, I have observed that Jmeter initiates thread after few seconds(depending on ramp up time).
If ramp up time is greater than 1 second, can I assume that number of threads set into the thread group are not concurrent??
