And that may be contributing to the CPU usage. Slowing down the flow may make the comouter more usable, and you're never going to copy 26TB quickly, especially over ethernet. > While I'm not sure what is keeping me from copying as fast as the drives > themselves can go, I suspect it is the encryption. If you're copying over the network, that will be the limiting factor. --=20 Neil Bothwick Nixon's Principal: If 2 wrongs don't make a right, try 3. --Sig_/JIsk6Se03sTRFd0raDRdY1F Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEGfLZTV7dXdQXh/dDdCdyyQfftocFAmUoF1QACgkQdCdyyQff toeDOhAAk0L5iptfU8NwNz54noVvD1AIDvM3Yxy035FvOTPelmdW7R5RnoFkX8Au bcQTB8lVUEJzkLV0PeYPVcdHibBfHMpal1EHuT3MdVBlPch3gfhH4Ld8zOtEGtAK 4TNFsrZu/ZxMNaTduRCFW0uhfek0u9+AjFoDJ80az0/4ExdeA2WQJRrPNYhtTfKw Y2VsMzxc/CX0v2f7Xl/Qcw2oBbZzir95UX2EUCAlqwZdWELIyIk0SPi41nfectud /LlsLt2HEq25yPUncMtJdclFVVZfDGIm5lDXsBAW0lWsFrHOlNX1LOZ8MPJKNuxO QRZ+SaE2p8qpSh9jcyQFv9LkDnTy+CBOm5zAIxHogb5qpZNq2Q9tMo+CGx/eOBVv XZNBQKvd5tXYye+pvN223gi9Dw2DNiQUHkthiS4YP8QrPSG1YSpK10WEUUlgBLkD yjr2DE2bttH4vBV1cFfNEqmqCUlLPRCHhspMFbfhsO1n8hGevOLAGaJrV9s8YNbB ubDp30pAlCyZw+fPIb5+08v+JJt/y7ek5FYGWZEUsHRB7n/evV7thIJAI3vrrFSW ywJh9I9RjCR5Hk+52oJxHtFcF9HqcTUEY+ijZx8Feed4OzOJBzHu+S1abmedUAdn Otl2iUrHycUPV4URPDmMytVVRbZJV5iPKE9+EIvLQLzGx4lhQBc= =I+Ki -----END PGP SIGNATURE----- --Sig_/JIsk6Se03sTRFd0raDRdY1F--
