Subject Re: tree cache load time

However, there is an optimization opportunity by using ZK’s multi-transactions. Maybe we
can explore this.

It would be largely dependent upon how much data you're caching. The tree cache needs to recursively
query ZK to populate the cache.

Hello All,
I am using tree cache for one of my project. Issue I am facing is with the time it is taking
for initialize itself. It is taking around 300ms to 3-4 s to load itself. 
This is how I am initializing the client and cache

 private val client = CuratorFrameworkFactory.newClient(hostList, new ExponentialBackoffRetry(ZookeeperCache.RetryInterval.toMillis.toInt,ZookeeperCache.RetryCount))

val cache = TreeCache.newBuilder(client, path).build()

post this I register for  a handler and then wait for "TreeCacheEvent.Type.INITIALIZED" event. 
It take on avg  300ms to 3-4 s.
IS there something I can do to improve this performance?
