From WA_WCC_Release_INCR1_ENU.pdf document installed by the patch
RO77628 ALL-WCC 11.3.6 INCREMENTAL 3

When installing CA WCC on UNIX or UNIX virtualized machines,
you may observe slower performance of Quick Edit, Quick View, Resource,
and Monitoring Flow applications.

The performance issue is a result of the low entropy needed for random number
generation used for internal CA WCC encryption procedures.

The workaround for this is to uncomment the line:

#wrapper.java.additional.101=-Djava.security.egd=file:/dev/./urandom
In both the WCC_Installation_Root files found at:

WCC_INSTALLATION_ROOT/tomcat/conf/wrapper.conf

and

WCC_INSTALLATION_ROOT/tomcat_32/conf/wrapper.conf
