I noticed the following passage in the release notes of gcc-4.5 (4.5-20100202-1), released in February.
"Configure with --enable-checking=yes for snapshot builds, and for 4.5 builds before the release."
Well gcc-4.5 was released about two months later, but gcc version 4.5.1 (Ubuntu 4.5.1-1ubuntu1) still uses --enable-checking=yes which slows down the compiler.
Binary package hint: gcc-4.5
