The memcached daemon is running on the same machine as the Fedora
instance, and the front end Django/Apache, and the OAI server and a
resolver. Phew.
Sounds like a lot, but: we have set up the configuration in such a
manner with multiple DNS aliases and Apache virtual hosts, so that if we
ever need to split things out to multiple machines for performance
reasons it should be relatively painless and the configuration should
not have to change much, except for updating our DNS entries to point at
different machines.

That sounds like a similar setup to what I'm working on.

 

I'm building the frontend on the Zend Framework and using its Zend_Cache
API to cache individual objects.  I'm presently using file caching in my
testing environment, but once we go to production, I'll likely switch
that to Memcached.  It's really easy to switch using the API (it just
requires changing a line or two of code).  I'm really happy with the
framework.

 

Do you have a dedicated Memcached server?

Are you serving up your front-end HTML views directly with Fedora, or is
there some other software between the Internet and your Fedora service?

 

We have a  Django-based frontend for submissions and administration,
with Fedora 3.x on the backend. There is an intermediate layer of
memcached which I use to cache object retrieval for display purposes, so
that every request doesn't have to fetch the data from Fedora again. Is
working pretty well in testing so far, but we are certainly not
anticipating any massive loads at this point in time.

I'm curious what sort of experiences anyone has had working with Fedora
3.* in a high traffic situation.  

 

Searching through the commons, I found this post: 

 

http://fedora-commons.org/confluence/display/FCKB/mail/8750419

 

which was posted back in 2004.  Has anyone put Fedora 3.* through any
similar benchmarks?

 

It's not that I anticipate any serious traffic, but I've been
considering using some sort of caching (possibly Memcached) for some of
our public collections just in case.  I'm just trying to ascertain how
necessary this is.
