I'm thinking of using multiple web servers with a load balancer in a big WP install. The database will be on a separate server and that's the easy part. Trickier is files in blogs.dir, and to a lesser extent, the themes and plugins folders.
So I plan to use a separate NFS server, either for all of wp_content or just for blogs.dir. But I'm worried about the performance impact of having these files available over the local network.
If you have done this I would love to hear your thoughts on...
- Is it wise to share all of wp-content in this way? If not, how about just blogs.dir?
- How much of a performance trade-off was it?
- Do you have any suggestions based on your experience?
