HP Enterprise File Services WAN Accelerator manual To enable Hstcp, Protocol support

Task	Description
Enable in-path support.	For detailed information, see “Enabling In-Path and Out-of-Path Support” on
	page 22.
Disable the Lempel-Ziv (LZ) compression	For detailed information about optimization policies if your WAN link capacity
and SDR in in-path optimization policies.	is 100 Mbps, see “Setting In-Path Rules” on page 25.
	With SDR enabled your throughput will bottleneck between 100 and 150
	Mbps, which cancels out the benefit of HSTCP. If you have an Optical Carrier-
	3 line or faster, turning off SDR makes sense and allows HSTCP to reach its
	full potential. For a 2 Mbps link, regardless of the amount of latency, it is better
	to keep SDR enabled, because the HSTCP mechanism is typically not triggered
	until you reach beyond 100 Mbps of WAN throughput.
