Large package sets seem to process slowly.

Default encryption level of ZLM 7 package processing causes slow deployment of packages.


To achieve greater speed in deployment of large package sets, the administrator can adjust the level of security provided by the connection between the client and the server. Adjusting the strength of the cypher suite from the default 256 bits to 128 bits will reduce the workload of the client, speeding up the resulting streaming of the packages to it.

To change the cypher suite to 128 bits, set the following attribute:


found in the tag for port 443
in the /etc/opt/novell/zenworks/tomcat/base/server.xml file on the ZLM server.

Setting this attribute will instruct the server to offer RC4 encryption at 128b as the only  available cypher suite, the client will comply as part of the SSL

It is necessary to restart the ZLM server after making this change.
