Was looking at reddit.com and found a blog post about ld.so.nohwcap. Is this something everyone has been doing and I just have been out of the loop?

Well probably there are not that many people out there with home directories (or application directories) on NFS shares. And on other systems the nohwcap hint probably doesn’t give that much of a performance boost, as I understand it.

Check the man page… nohwcap is not something most folks want. It’s going to prevent your applications from using a C library that takes advantage of your CPU’s special hardware capabilities.
In general, this will lead to a performance decrease. Expect that apps that use threads will face more serious penalties without those CPU features for thread local storage and whatnot.

Any examples? I don’t see any libraries on my system that there are multiple architectures that benefit me that are compiled?

FYI, your link wasn’t a permanent link to an article and now the nohwcap article has moved off of that link. I found this page by reference and after digging around, was able to find this permalink: http://saintaardvarkthecarpeted.com/blog/archive/2005/08/_etc_ld_so_nohwcap.html
