I asked about increasing it and was told that it can be done by editing a value in one of the .h files or something, but the reason it wasn't higher was that it didn't scale nicely, and they wanted to reword how it works. I would definitely be interested in this, as we run video transcoding (uses a LOT of cpu) on 24 or 32 core machines, and we'd like to pass more of the cores into the VM. --=20 Allan Jude --KVtpGp9rSRNLrAfr8WMU00m3bSRPs7BIt Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.16 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBAgAGBQJTjmbFAAoJEJrBFpNRJZKfQGAQAKW+q1+G5sWNJVE6L0ovEa60 /aLPSp6feZ2lgzlEsFLNprkhkKuJfABjSDzuvJkcRjlusuwH2vtetjYBpqxYCFWU SIGvidMArylLLlcdecRHj8VPAVkOcE9Oam9EpOCx9glkgwwyKxKUTEW+sp5/i2LS ZA8zNVlZkPVBZuJpJykSW0A5lgeeEMk0tgN2Z+SiQaH7UcH5i2BPUXxHIV7QfX3d leTqtWHAgUxBwLmCebEiNbMjjF/Pwn3nbR/7eQt8+rPfLVR4kJZU5tUz2pILexrK P/FlgSY3uIysDLRe1ng73DbgOmmdVF4rRn6MQr8fMqyZOXz6AYXbLCQU2yxznbmW w+MYpP0o3UJ3tA57g1LU0c/YnoCjtN/5KqeH/jK37GY/PPiv/u8xpKpXaLKRfgGI X2J+3RvY1d4JloQYdNplLMiON0FpHrPkyJ1c7MtOgXkh0ZBGlQFBgLthDG9WZgbw x/HXWCvNqssYEyTK0uEs2YmSCM33Qvef5pP7RbFCQ13kiHBp84TcLgYt99//TZ1z vn+NSaqSGRI9STvcZviLzS2MRak/wY407XAZgPvtgpqAnjWyEVTiL9xbTz/IrWOi 7cZOedFhb1qGNC2zSVcw5cHPST7V5+JJYkCj2KyUTB2NCD4SYbbl6MpvM6uw1tm1 DZlZM+r6fIoUaodjO7TP =vAZ1 -----END PGP SIGNATURE----- --KVtpGp9rSRNLrAfr8WMU00m3bSRPs7BIt--
