How to analyze a JMeter summary report?

Question

I get the following result when I run a load test. Can any one help me to read the report?

the number of thread = '500 '
ramp up period = '1'

Sample      =       '500'
Avg     =       '20917'
min         =       '820'
max         =       '48158'
Std Deviation   =       '10563.178194669255'
Error %     =       '0.046'
throughput      =       '10.375381295262601'
KB/Sec          =       `247.05023046315702` 
Avg. Bytes      =       '24382.664'

Answer 1

Short explanation looks like:

1. Sample - number of requests sent
2. Avg - an Arithmetic mean for all responses (sum of all times / count)
3. Minimal response time (ms)
4. Maximum response time (ms)
5. Deviation - see Standard Deviation article
6. Error rate - percentage of failed tests
7. Throughput - how many requests per second does your server handle. Larger is better.
8. KB/Sec - self expalanatory
9. Avg. Bytes - average response size
