W3 Total Cache
Using W3 with Load Balanced Servers (2 posts)

    Hi,

    We're moving away from our single dedicated server to a load balanced environment and I have a few questions/thoughts on how this will potentially work.

    Setup:
    (2) Apache2 front-end servers (ie. www1, www2)
    (1) MySQL server also running Memcached (ie. www3)

    I'm thinking we would use W3 on both servers Apache servers:
    - Page Cache would use Memcache on www3
    - Database Cache would use Memcache on www3
    - Object Cache would use Memcache on www3

    How we determine how to handle content uploads is an entirely different beast and is off-topic I believe for this thread. However, for the sake of keeping OT, for Object Cache could we use APC installed on both boxes instead of Memcache on www3? I assume that APC is just keeping PHP scripts for WordPress compiled in memory. Is there any benefit of APC locally on each box or using Memcache on a central server?

    Thanks in advance for any feedback.

    Best,
    Cent

    This topic is too advanced for the forums. As it stands when using multiple servers you will need to use memcached unless you are capable of mix and match configurations. For uploads a shared resource is likely necessary like network file share (NFS).
