Ticket #8369 (closed defect: obsolete)
NAT: CIFS connection to host is terribly slow
|Reported by:||birdie||Owned by:|
Description (last modified by frank) (diff)
Probably NAT is not meant for transferring data between host OS and guest OS, but since it's possible I suppose such a connection should have a speed comparable to Host-only connection.
However it's not the case.
When copying data from Fedora 14 guest to Fedora 14 host (both have i686 arch) I get 196KB/sec connection speed on average. Both hosts are 100% idle when copying (host OS exports SMB shares, guest OS has them mounted via CIFS).
When I copy data using Host-only adapter the speed soars to 20-30MB/sec.
P.S. Guest additions are not installed. Guest OS has Intel PRO/1000MT Desktop (82540EM) adapter.
- Summary changed from NAT connection to host is terribly slow to NAT: CIFS connection to host is terribly slow
