Subject [jira] [Commented] (DISPATCH-218) Dispatch system tests run very slowly if connected to a VPN
Date Fri, 19 Feb 2016 13:38:18 GMT

    [ https://issues.apache.org/jira/browse/DISPATCH-218?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15154214#comment-15154214

Alan Conway commented on DISPATCH-218:
--------------------------------------

The LDAP lookups were caused by my sssd.conf setup which was looking up user names via LDAP.
It is not clear *why* qdrouterd would do this on start-up before any connections are made.
I can eliminate them by disabling ldap in /etc/sssd.conf or with `authconfig --disableldap
--updateall` or by stopping sssd.

We still need to investigate whether all these calls are *necessary* in an LDAP-enabled environment.
It's ok for the security layer to do extra work when that is needed, but it is not ok for
the mere presence of the security layer to add significant overhead even when it is not being
used.

> The dispatch system tests (e.g. system_tests_management) run very slowly when connected
to a VPN.
> -  about 10x slower on VPN configured to use TCP connection
> -  about 5x slower on VPN configured for UDP connection
> Wireshark shows unexpected LDAP and DNS queries on the VPN interface. `wallace` below
is the local host name, but is not mentioned in any tests so must be picked up by proton or
dispatch at runtime:
> {code}
> 1	0.000000000	10.3.113.108	10.11.6.1	LDAP	242	searchRequest(11) "dc=redhat,dc=com" wholeSubtree

> 2	0.035161000	10.3.113.108	10.5.30.160	DNS	72	Standard query 0xd03f  A wallace.lab.bos.redhat.com
> {code}
