JMeter sends https request delayed due to netbios lookup
Hi Experts,
I encountered one issue that when JMeter sends a https request to server, it
cost mostly 4 seconds during the session, it’s too long……. I had captured
the packet data by wireshark, you can have a look below or attachment.
Source IP(https client-JMeter):10.68.33.195
Destination IP(https server):10.125.199.69
For packet #1037, #1252 and #1404, JMeter tried 3 times to do netbios
lookup, it cost 3 seconds, it’s unexpected for me;
But the server side handle the https request quickly, it cost around 0.1s,
it’s expected for me.
Thanks,
Weidong

Hello,
Read this thread related to the bugzilla:
http://mail-archives.apache.org/mod_mbox/hc-httpclient-users/201408.mbox/%3C1409125976.11799.4.camel%40ubuntu%3E
The issue in JDK is not fixed, it is marked as not an issue.
As explained in the discussion
java.net.Inet4AddressImpl.getHostByAddr attempts a reverse lookup.
Now as Bohdan explains, the defaulting to Netbios might be explained
by this, but I am not sure.
But I am very interested by your feedback once you do what Bohdan advises.
Regards
Philippe

RE: JMeter sends https request delayed due to netbios lookup
Posted by "BOLB (Bohdan L Bodnar)" <BO...@panduit.com>.
I ran across a similar problem a bit over a year ago. The solution was to configure the DNS server for correct reverse-DNS queries. NETBIOS is used only when Windows can't get information from the DNS server.

You maybe facing this issue:
- <https://issues.apache.org/bugzilla/show_bug.cgi?id=54449>
https://issues.apache.org/bugzilla/show_bug.cgi?id=54449
There is currently a discussion on dev list related to how httpclient 4.2.3 uses INetaddress.getHostByName (which makes reverse lookup that could explain this issue) and could use a new method from jdk7.
Can you attach all details you jave on this issue if you are in the same conditions.

Re: JMeter sends https request delayed due to netbios lookup
Posted by Philippe Mouawad <ph...@gmail.com>.
Hello,
You maybe facing this issue:
- https://issues.apache.org/bugzilla/show_bug.cgi?id=54449
There is currently a discussion on dev list related to how httpclient 4.2.3
uses INetaddress.getHostByName (which makes reverse lookup that could
explain this issue) and could use a new method from jdk7.
Can you attach all details you jave on this issue if you are in the same
conditions.
Regards
Philippe M.

I didn't notice I sent email directly to you.
Better continue communication at the users list.
Not sure why HC4 behaves like that.
Maybe someone else can explain.

答复: JMeter sends https request delayed due to netbios lookup
Posted by "张为东(为东)" <we...@alibaba-inc.com>.
Shmuel, I’d like to figure out the reason why JMeter sends netbios lookup 3 times in this case.
On the other hand, I think it’s not related to the connection timeout, the server side works well, the client side cost more seconds to send next packet.

As you can see - it failed to connect the destination host.
You should be able to control the connect part to timeout if it doesn't get a valid connection in a shorter time via the Connect Timeout:

JMeter sends https request delayed due to netbios lookup
Posted by "张为东(为东)" <we...@alibaba-inc.com>.
Hi Experts,
I encountered one issue that when JMeter sends a https request to server, it
cost mostly 4 seconds during the session, it’s too long……. I had captured
the packet data by wireshark, you can have a look below or attachment.
Source IP(https client-JMeter):10.68.33.195
Destination IP(https server):10.125.199.69
For packet #1037, #1252 and #1404, JMeter tried 3 times to do netbios
lookup, it cost 3 seconds, it’s unexpected for me;
But the server side handle the https request quickly, it cost around 0.1s,
it’s expected for me.
Thanks,
Weidong
