environment: Hobbit 4.2 with allinone patch on RHEL5.1 It appears that using the https tag and defining a port introduces 50-200ms of latency to the results of all bbnet-tests. I had the following tag working fine for months in bb-hosts: cont=kvm;https://server.domain.com/dsview/protected/login.do;Avocent The need came up to move this particular webserver to a non-standard ssl port: cont=kvm;https://server.domain.com:9443/dsview/protected/login.do;Avocent As soon as I did this 'all' TCP graphs, http, ldap, smtp, etc... had a new plateau 50-200ms higher. I ran bbnet-test with the --debug and --timing options but didn't see anything out of the ordinary, then again I don't know what I should be looking for that would help to resolve it. Let me know what you want and I'll provide it. I was able to duplicate the problem on a separate dev hobbit server as well.
I have no idea what could cause this, but I dont see anything in the Hobbit code that could account for it. The port number for each test is determined in advance, before the tests begin. So the codepath used to perform a network connection does not depend on the test using a default or non-default portnumber.
Is there any kind of firewall between your Hobbit server and the system(s) you're testing ?
No, there is no firewall between the boxes.
I was able to duplicate the problem using a basic apache/mod_ssl setup to using port: 9443 to rule out the possibility of the Avocent/jeti webserver causing problems.
I baselined the test with the following tag in bb-hosts: 192.168.1.210 server01.domain.com # http://server01.domain.com
Then added the https tag: 192.168.1.210 server01.domain.com # http://server01.domain.com https://server01.domain.com:9443/
And observed the same 50+ plateau jump on the graph for the original test.
