resources using mhash

[Russell Dickson]

I hope this is the correct list for this.

I'm wondering about mhash and how others find it for efficiency on a web
server, specifically for RAM and how much it adds to the web daemon.  Also,
if anyone has found a problem when recompiling it in with PHP?  I can't
find any such stats and little else on mhash.  

My server is on FreeBSD 4.7-REL, Apache 1.23.55 and PHP 4.2.3.  The mhash
extension is needed to connect with Authorize.Net's new system.  I'm new to
FreeBSD, the guy handling my server is not, though he's not familiar with
mhash.

Thanks in advance,

Russell
