I found weird thing. if I run 2 virtualbox such as 2 windows 7 or 1 windows 7/ 1 windows 8 at the same time, then both VMs get faster, I am running 1 win7 32bit and 1 win8 64 bit.. then both got faster, both are reasonably good to use/run a program.. 1 VM is much slower than 2 simultaneous VMs !! 2012/11/21 =C1=F8=BC=AE=BF=C0 <jsukoh@gmail.com> > Dear, > > I installed virtualbox 4.2.4(CFT) on zfs FreeBSD 9.1-RC3 > > installing and windows guest(windows 8) install with guest addition was > successful. > but the windows guest is too slow, it is hardly usable. > > my hardware specs. > intel i7 quad core 3.6. ghz, with 8 thread > mem 16G > motherboard - asrock z79 extreme 6. > intel SSD 120G. > > > my virtualbox vdi file is at zroot/bigfile, with > primaryache, secondarycache =3D NONE, even sync=3Ddisabled because of slo= w > performance. > > virtual machine settings > - mem 4096M, cpu 4ea > - 25g vdi(SATA controller) with SSD ticked > - VT-x/AMD-V, Nested Paging > - video 128M > > > > I tried the VB on UFS because ZFS was too slow, but the result was the > same.. > I downgraded to FreeBSD 9.0 on UFS or / ZFS, but but the result was the > same.. > and I tried virtualbox 4.1.22 on FB 9.0/9.1-RC3,but but the result was > the same.. > > but sad story is that > I found that virtualbox 4.2.4 on linux(opensuse 12.2, ext4) was very fast= . > opensuse is installed on the second harddisk(NOT SSD) at the same comput= er. > > virtualbox zfs/FreeBSD on SSD is much slower than virtualbox ext4/opensus= e > on SATA2 harddisk... > > > do I have any miss to setup on FreeBSD?
