This is a rather surprising result. With any release there are things that change, so it could be related to a change in the compiler, it could also be related to something that "just happened to work" with the previous version - for example an uninitialised variable.
To resolve this I would suggest profiling the application using the performance analyzer and determining where the slowdown occurs. With a slowdown of this magnitude, the location should be readily apparent.
Thanks for the suggestion. My collect command (<..>//solstudio12.2/bin/collect) gives the following output:
WARNING: Linux-64-bit, 4 CPUs, LinuxMint_9 system "mymachine" is not supported by the Performance tools.
NOTE: The J2SE[tm] version 1.6.0_22 found at /usr/lib/jvm/java-6-sun/bin/java (picked by JDK_HOME) is supported by the Performance tools.
WARNING: Data collection may fail: system is not properly configured or is unsupported.
Does this indicate that I can not use performance analyzer on my x86_64 Linux platform.

It means that the performance analyzer might fail. If you get the data - it worked, if there's no data it didn't... The supported platforms for 12.2 are:
- SuSE Linux Enterprise Server 11
- RedHat Enterprise Linux 5
- Oracle Enterprise Linux 5
