It depends. Generally speaking, if you run "a bunch" of net apps, HTT should be beneficial for response time, however, it will hinder those applications that don't utilize threading and is CPU intensive. A ``systat -vm'' can give you some useful information what your application is like. If applications needs to sleep and wait for I/O, then turning on HTT may result in better performance.=20 Cheers, --=20 Xin LI http://www.delphij.net/ See complete headers for GPG key and other information. --PEIAKu/WMn1b1Hv9 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) iD8DBQFBkIPQ/cVsHxFZiIoRAtNpAJ9fzhX+IMphP8iLc2fA9ddt/l9aeACfbRUL v3wdRwa0FnNeXSiFrLANyfI= =VuI9 -----END PGP SIGNATURE----- --PEIAKu/WMn1b1Hv9--
