the Integration and Connectivity Kit includes a version of xep.jar with
debugging information turned on. A part of the debugger is a static
logger which synchronized methods. Are you using by any chance the jar
from the Kit?

The production jar is the same in all the functionality except that it
does not print full stack traces and does not have that static
synchronized logger which is the only possible cause for contention you
are mentioning.
