Yes, your understanding is correct. But, since the objects are only passively moved over, you have to have cluster gets enabled.
This hasn't been a performance issue for me. The extra remote get for misses doesn't add much (<10ms in most setups). I always setup a null object cache, so we don't go looking for bad keys more than once. . . Aaron --- [EMAIL PROTECTED] wrote: > So far, this is working.
