Status of UserspaceIOCPBuffers ??
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 So in the documentation: UserspaceIOCPBuffers 0|1 If IOCP is enabled (see DisableIOCP above), setting this option to 1 will tell Tor to disable kernel-space TCP buffers, in order to avoid needless copy operations and try not to run out of non-paged RAM. This feature is experimental; don’t use it yet unless you’re eager to help tracking down bugs. (Default: 0) Is this description still accurate, or is it better debugged nowadays? Would this be useful to set on machines with limited memory resources, e.g. the Raspberry Pi? Thanks much for any insight. - -Gordon M. -----BEGIN PGP SIGNATURE----- iQEcBAEBCgAGBQJSJMrDAAoJED/jpRoe7/ujZX8IALXnFOs6WEQsud4UChnjdDRC Cor6LScDdXjGBvRDodMxyrF6lX50SwIaBR+zu4I4Hw2ekit8UZdBdZafWSjQgq5W KdMW1XruYBEIN2OcWSjSoZ1K2DzuOr1O77JwBhCuRcJtqqIP5yfD2TcF6AmuxHWk 82is5XCppem1b3CVobduKIVvbC6vUu+3fau5jkwrRv0xVQGTEtSWRY9TDFP5hoxB cZN+N2yYAm0pZ9+X1fFOHteKOx9r8ENsHfSCeZfKJXbbeRmklxVnZ1k3AgU2BiET L2tVs/piMOkhOd/hGX59bRk/IyvxArmXxd5+Vq9ejLZa7nmKMuOfZYbKdGo+zlE= =b1Os -----END PGP SIGNATURE-----

It's still correct.
Would this be useful to set on machines with limited memory resources, e.g. the Raspberry Pi?
Probably not -- it has no effect except on Windows. -- Nick
