batch archiving is too slow for my computer ... is it really intensive?

[Samuel Wales]

maint.

i have an old computer, which usually has no problems if i am careful,
except org is recently somewhat slower.

with agenda batch archiving, however, even for just a few entries, the
cpu overheats.

the cpu never gets above 28% in a dual core in gkrellm, meaning that
only 1/4 of total capacity in a dual core is used.  i don't know why
that makes it overheat.

here is a profiler report for archiving 2 entries.  then 2 entries again.

is this kind of a normal profiler report?

thanks.
