openssl ships optimized libraries for some cpus. The loading of these
|
||
|
|
libraries depends on the ability of the dynamic linker to automaticly
|
||
|
|
search additional directories depending on the cpu. If you want to
|
||
|
|
find out which are these directories for your computer, run the
|
||
|
|
following command:
|
||
|
|
|
||
|
|
LD_LIBRARY_PATH=/usr/lib strace true 2>&1 | fgrep "open(\"/usr/lib"
|
||
|
|
|

On a Pentium III this gives:
|
||
|
|
|
||
|
|
open("/usr/lib/i686/mmx/libc.so.6", O_RDONLY) = -1 ENOENT (No such file or directory)
|
||
|
|
open("/usr/lib/i686/libc.so.6", O_RDONLY) = -1 ENOENT (No such file or directory)
|
||
|
|
open("/usr/lib/mmx/libc.so.6", O_RDONLY) = -1 ENOENT (No such file or directory)
|
||
|
|
open("/usr/lib/libc.so.6", O_RDONLY) = -1 ENOENT (No such file or directory)
|
||
|

Following is a list of cpus, library paths and possible optimizations:

+asm means that the handcrafted 586 assembler routines can be used.
