Subject: XA transactions much slower on 14.2 than on 13.5

My boss asked me to upgrade one of the development databases from 13.5
--> 14.2. One thing that we've noticed right away is that XA
transactions (2-phase commit) are much slower on 14.2 than on 13.5. Were
there any significant changes to the XA protocol in the version 14? Did
anybody else encountered this problem?
When I say "XA transactions are much slower", I mean that commit and/or
rollback take much longer. The SQL execution takes the same and the
plans are identical to the 13.5 version. The application code is the
same, using IBM WebSphere 9.0.4.
