Here are results for texmacs with its libraries.
I have launched oprofile with separate library profiling:
# opcontrol --setup --no-vmlinux --event=DATA_CACHE_MISSES:2000
--event=DATA_CACHE_ACCESSES:2000 --event=DATA_CACHE_REFILLS_FROM_L2:2000:0x1f
--event=DATA_CACHE_REFILLS_FROM_SYSTEM:2000:0x1f -p=library
$ opreport event:DATA_CACHE_MISSES,DATA_CACHE_ACCESSES image:*texmacs*
CPU: Athlon, speed 1826.62 MHz (estimated)
Counted DATA_CACHE_ACCESSES events (Data cache accesses) with a unit mask of
0x00 (No unit mask) count 2000
Counted DATA_CACHE_MISSES events (Data cache misses) with a unit mask of 0x00
(No unit mask) count 2000

Guile is a big source of cache misses.
Yours,
