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?
