Max times values are very High

Sumit Verma
Hi,

I have run a performance tests for my service. I can see response times at
my service ends are well within 1 sec but in the Jmeter aggregate reports
max time values are very high(more 60 secs).

What could be the reasons for such high numbers?

Thanks in Advance.

What is the socket timeout set for?  Is the service taking a very long time using queuing or a long time for data look up?  There could be many reasons for this, I would suggest working with development to track the long transaction time.  Also logs would help if you use spluk or kibana this may help diagnosis the issue.

Hi Bob,

Thanks for responding.
We are using New Relic to monitor service timings. At service end, I could
not find any request with time > 800 ms. But at client(Jmeter) end, some
requests are surprisingly taking more than 10 seconds. Could it be
limitation of Jmeter?

Thanks,
Sumit

Re: Max times values are very High

Bo Bodnar-2

Now we've details as to the experiments. Perhaps, you're seeing network issues? I'd run something like t-shark or wireshark on the computer running jmeter and see what it shows. Out network guru has seen something like this happen very infrequently during controlled experiments. The root cause was either a misconfigured switch or router in the core network. I've also seen similar things with optic networks where the laser in the NIC begins to degrade; a symptom is a burst of TCP timeouts.

You may also want to check if ipv6 dns queries are failing because the server or your proxy does not allow them so some need to wait for the timeout before some transactions will continue? You may need to permantly disable ipv6 to resolve the issue.

Re: Max times values are very High

ra0077
Hi,

Check if the server where JMeter is running is ok (cpu, memory...)

Next check if Newrelic capture all transaction (some profiler make sampling
and don't capture all the transaction)

Finally, check the network like said before
