I just setup hugepages (1024 pages a 2 MB) according this hint
http://www.pythian.com/news/1326/performance-tuning-hugepages-in-linux/

anonymizer2:~# echo 1024 > /proc/sys/vm/nr_hugepages
anonymizer2:~# cat /proc/meminfo | grep -i hugepage
HugePages_Total:     126
HugePages_Free:      126
HugePages_Rsvd:        0
HugePages_Surp:        0
Hugepagesize:       2048 kB

Does tor process automagically take advantage from hugepages after
restarting the process or has tor source code to be modified?

regards Olaf
