Now the benchmark results :Firebird 2.5 seems that clang++ is faster!

clean run , the old llvm results were when the system was under high load
now i have the clean results and seems that clang++ is faster

clean run

running on the g++ (compiled from source)

clang++ fronm ubuntu 10.10

after each run i have run the following scripts

cat killall.sh
sudo killall -9 fbguard
sudo killall -9 fbserver
cat delete.sh
sudo rm -rf /opt/firebird2.5
sudo rm -rf /etc/init.d/firebird
cat config.sh
make clean
rm -rf gen
./configure --prefix=/opt/firebird2.5 --enable-superserver
--with-system-icu --with-system-editline

sudo make install

(in the firebird 2.5 from subversion tree)

ps:
make install doesn't work quite correctly in g++ and clang++ there are
some bugs on ubuntu 10.10
I have to CTRL-C the installer after i put the password , so i will
mark it as bug in jira for both compilers
