The host or the guest or both? Hi, only inside VirtualBox, I think it's only an application problem and my emails would be probably better addressed to ports@. ONLY the guest is affected when host is loaded. I noticed additionally: You get better results with a desync'ed clock in the guest system, when you start "openssl speed -multi 20" or similar. Within a few seconds the clock gets a 20 seconds difference. > How many CPU's did you assign to the guest? > Did you install virtualbox guest additions to the guest? Here a few details (guest additions are installed): Memory size: 1600MB Page Fusion: off VRAM size: 256MB HPET: on/off (tried both settings) Chipset: piix3 Firmware: BIOS Number of CPUs: 1 Synthetic Cpu: off CPUID overrides: None [...] ACPI: on IOAPIC: off PAE: on Time offset: 0 ms RTC: local time Hardw. virt.ext: on Hardw. virt.ext exclusive: on Nested Paging: on Large Pages: on VT-x VPID: on [...] 3D Acceleration: off 2D Video Acceleration: on > Do you run NTP on the guest XP also? If yes, turn it off. Windows XP default installation (synch'ed to time.windows.com). Switching this off, does not have any influence. I think MS-Windows does not do continuous synchronization, only at system start, I guess. > VBox guest additions can sync the guest clock with the host. I'll try to deinstall them. But I somehow like my shared folder. > BTW: My experience with VBox is that it is nice for hobby stuff, but > not for heavy load server stuff. VMWare does a better job there. Yes. I know. Still VirtualBox ist nice and cheap solution. -- Martin --Sig_/A1JvsXCjPKdNieBoKjOmuEX Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iQIcBAEBAgAGBQJPGrmbAAoJEF8wvLx/5p/7CTwQAMb6a5t3LPJeU0WlAJS7EFQk YVGyIHiK3iBvrIeOoSUc+KNM7Aso3pc/YZGsZnjTUDDiG3Px4ENaJensOaH72A6Y bKTtqrSGgvVcUrwCLeY7P6DefsqUyEpLI+zBaTu2NDbnHYdCtwbRlOGJqm9IdcQF O6hRihkA3ZRSqU400D4xVNsDDqd0G2seHMu+Yiw8s4vJUVETwUUVN6+65qfdpLGv XIj5+ZzIRVeQoHaJahHLSznO6ea6zxlJ39KP2tzenuGxT1Mr1tjX1tIUr2SMO7U6 iowznGynLmTd12jdORrWjQBIu2S2ldjNlu0AQ+SNk0VgcDNg/FqA5O98fzV+tXDd 587XiaeHoCR/ZjlAnS0Jv6lukdzySaqfE7f/JGyQ1is0HYpdTUNf1fIqB4ujgTNE 28rsPQZIcHBDtR6NWjcgOtbr3pDURGfXBDS7aFzgUShMfV4UwHVRqApqlyu71G38 QgB86f4/+1NHlcLhML+03ij/mkMv/dHOW7bQiMmwoWgJTnXzSn4XpwCrHIano134 pVLxxbxvcQrfpJFJIn8SXLTeOHryBfBjJufKE4eUF7drOp2mzcJpF4korYcVuWDp WCXluJXqaTOs2LeLK/9JuyhAgHon4NZXdx5z0t1H2ViMrkQoW5fFZ0ctp6jtOOfB rg4wANlwslC2Kt16UD6b =jNAf -----END PGP SIGNATURE----- --Sig_/A1JvsXCjPKdNieBoKjOmuEX--
