I have detected aprox. 7% performance regression in camel-cxf-proxy-xslt integration example on EAP. Problem is monitored against fuse version 7.2.0 035. When comparing performance of 7.3.0 059 and 7.2.0 035 the performance drop is only 4.16 %, therefore between 7.3.0 059 and fuse 7.3 CR1 it's another 3.48 % drop.

Performance test results are here
