Subject: Announcement: TUX 2.0
TUX 2.0 is now available for download at the following URL:
The TUX 2.0 release is an incremental upgrade to TUX 1.0 and
keeps source-code level compatibility with user-space modules.
A number of incremental enhancements have been made:
- True zero-copy disk reads: Whereas TUX 1.0 copied files into a
temporary buffer, TUX 2.0 is integrated with the page cache and
thus uses zero-copy block IO.
- Generic zero-copy network writes: TUX 2.0 uses the generic
zero-copy TCP framework.
- Zero-copy parsing: Where possible, TUX parses input packets
directly. Even in RAM-limited situations, TUX now does full,
back-to-back zero-copy I/O.
Other changes include:
- Enhanced user-space utilities and module support.
- Mass virtual hosting support. The host-based virtual server
patch has been added to TUX. There is no limit on the number of
virtual hosts supported, only RAM and diskspace.
- CGIs can be bound to particular CPUs or can be left
- A number of bugs were fixed which caused performance problems
- TUX 2.0 is now significantly faster than TUX 1.0!
