For example, SQL performance when using ext4 basically sucks in both Jaunty and Karmic. This is a Kernel bug and won't be addressed until the next release.
The included mesa build in ubuntu also includes the new code path for ATi cards (the memory manager, some gallium stuff, the 3D rewrite...). While this will pay off in terms of performance and bugs for Lucid (10.04), the current 3D performance in ATi cards not supported by fglrx (Radeon X1950 an earlier) is in general slower than in Jaunty.
Finally, updating from Jaunty produces a considerably slower boot in systems using conventional hard drives. At least that's what I've seen in three different laptops. It is possible to mitigate this and even turn it around by enabling the karmic-proposed updates and installing ureadahead, though.
EDIT: If you compile your software, Karmic comes with gcc 4.4. GCC keeps getting stricter every day, and you may need some source code wizardry if the code you are interested in isn't totally ISO compliant.
I ordered another 500GB hdd to slide into my box to dual install Ubuntu to run this software. With it installed in a Virtual Machine, I have HUGE issues getting my dual 4870x2's to co-operate. It won't even let me install the 9.10 catalyst drivers!
With all of the issues that I have had with CAE-Linux so far, it is something worthwhile enough that I just dropped $60 for a dedicated HDD (It does not want to install to my 2TB RAID array), I just hope that it will allow me to harness the hardware that I have in that box!
