DetailsDescription:
Extract from http://httpd.apache.org/docs/2.2/misc/perf-tuning.html#compiletime: Linux on x86 By default, APR uses mutex-based atomics on Linux. If you configure with --enable-nonportable-atomics, however, APR generates code that uses a 486 opcode for fast hardware compare-and-swap. This will result in more efficient atomic operations, but the resulting executable will run only on 486 and later chips (and not on 386). Additional info: * 1.2.8 and the soon to be 1.2.9 are both affected, as they default to the i386 compatible code. As Arch is targeted for i686, I suggest adding this configure option to apr. |
