	If you see a large amount of LZ Bypass traffic, this could be due to a large amount of encrypted traffic, which is not generally compressible.		If you see a large amount of LZ Bypass traffic, this could be due to a large amount of encrypted traffic, which is not generally compressible.

-	The Average latency numbers can be useful for debugging a throughput issue. ~~Both~~ the encode and decode average latency ~~should generally be less than 30~~ ms. If users experience low throughput and one or both of these numbers are higher, it indicates an issue with encoding or decoding, generally on the side with the higher latency.	+	The Average latency numbers can be useful for debugging a throughput issue. Depending on the platform, both the encode and decode average latency are typically in the single digits of ms. If users experience low throughput and one or both of these numbers are higher, it indicates an issue with encoding or decoding, generally on the side with the higher latency.

	It may be useful to look at the DRE statistics data such as the oldest usable data, cache size, percent of cache used, hash table RAM used, and so on by using the '''show statistics dre detail''' command, as follows:		It may be useful to look at the DRE statistics data such as the oldest usable data, cache size, percent of cache used, hash table RAM used, and so on by using the '''show statistics dre detail''' command, as follows:

	In the Policy Engine Statistics section of the output, the Rejected Connection Counts section show various reasons why connections have been rejected. The Connection Limit counter reports the number of times that a connection has been rejected because the maximum number of optimized connections has been exceeded. If you see a high number here, you should look into overload conditions.
