--0003255765aedd4d27049c7de941 Content-Type: text/plain; charset=ISO-8859-1 Hi, I wanted to know if DragonFlyBSD supports Hyper threading or not. I did some benchmarking recently and it seems that on a Xeon dual core with 2 virtual cpu per core, DFBSD only scale to 2 threads and after that the number of transactions/second dorps (using sysbench oltp). So does that mean DFBSD does not support Hyperthreading !? If that is the case, I need to perform the benchmarks on a different machine without hyper threading. Please kindly advise. Thanks, Saman Barghi --0003255765aedd4d27049c7de941 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr">Hi, <br>I wanted to know if DragonFlyBSD supports Hyper th= reading or not.
