Note: there are documented total VPN throughput restrictions on the
506E, 515, and 515E, that are noticably lower than the figures given above. The documentation might not reflect the use of VAC/VAC+. Also, the document was the "506E/515E Q&A" from the 6.1(2) timeframe, but 6.2 introduced substantial VPN speedups for at least some of the systems (e.g., 501), so the data in that document may be obsolete.
