We have a semi-large web-server farm and use NFS on the back-end to distribute content (we have lots of sites running on multiple boxes). The back-end NFS server is doing ok, but it is usually running at about 3000 NFSops with a cpu utilization of 50-70%. Our avg cache age is 4 minutes. We are using a f540 with 256MB of read-cache, and use fddi for the nfs network.
Our content is updated throughout the day. But most folks hit the same pages over time. Every page has an advertisement or 2.
I see a few different ways of extending the life of the back-end server, and these may involve:
- cachefs (on the client) - squid or harvest (as a web cache)
Has anybody out there already done such an analysis of caching? We have about 50GB of content.
Are there other solutions out there that may also help?
We are a homogenous Sun shop.
I have used harvest before, but not across virtual hosts.
Upgrading to a f630 is an option, but it would probably take forever to move the content (as well as consume the filer).
Anybody out ther done testing on any of these pieces?
Thanks.
