The primary goal of this research is to improve
the scalability and robustness of the Linux operating system
to support greater network server workloads more reliably.
We are specifically interested
in single-system scalability, performance,
and reliability of network server
infrastructure products running on Linux, such as
LDAP directory servers,
IMAP electronic mail servers,
and web servers, among others.
We focused on building our web server test harness during
the last two months.
We've been joined by new staff and new sponsors.
We're continuing to reach out to potential sponsors.
Work continues on long-term projects.
Intel delivered a four CPU SC450NX server for use
in our test harness.
We intend to add disks and high-bandwidth networking
to support RAID and gigabit networking capability.
Brian Hernacki, release manager for the Netscape
Messaging Server version 4.15, has offered to
help us install MS 4.15 and a mail benchmarking
system so we can begin stress-testing the mail
server on Linux here at CITI.
Andy continues to develop an NFSv4 implementation,
now based on the Linux 2.2.10 NFSv3 implementation.
Compound RPC is working, and enough RPCs have been
implemented that it is possible to mount via the
NFSv4 protocol, sans mountd.
Andy is now focusing on implementing the NFSv4
Niels has ported his hinting poll() patch to a
recent 2.3 kernel, and is working on removing
the socket count constraint in the 2.2 TCP
We are hoping to get both patches into the
Linux kernel before 2.4 is released.
Chuck has developed some patches that fix problems in
the new write-through page cache introduced in the
He continues to work on an madvise() system call and
read-ahead for mmap-ed files.
Chuck attended LinuxWorld Expo in San Jose, and
visited Mountain View to discuss next-release issues
with Netscape developers.
Chuck will continue to increase his involvement
with immediate product developement over the next
Steve continues to explore thundering herd
issues in the Linux TCP stack.
Jonathan is reviewing the Linux scheduler, and is
exploring ways to improve it's performance.
We're expecting to hire a new graduate student
Peter visited Holland to discuss further funding
alternatives with Stichting NLNet staff.
Red Hat continues to respond positively
towards our overtures for gaining project funding.
The Dangers of Growing Linux Market Share
Recently, Freshmeat.net published an "Open Letter to Red
Hat and Robert Young," written by Robert W. Current.
I think it raises some interesting points, so
