z-push load problem

[John McMonagle]

Running kolab 2.2.4
z-push-1.5-0.2.beta2
PEAR-Kolab_Zpush-0.1.2-1
kolab-z-push-0.7.3-1

Someone bought a Motorola Photon from Sprint with Android 2.3.
It syncs fine but it puts a nasty load on the kolab  server.
As I recall being in push mode does that.
I see nothing in it's Corporate Sync" settings to change sync schedule.

I plan on upgrading kolab to 2.3.4 in a few weeks.
Does 2.3.4 handle push?
Any recommendations?
