- So, you want vsftpd to go quickly?
- Here are some random assorted performance tips.
- 1) vsftpd thrives because of its lightweight RSS and vm usage. If you run
- a glibc based system (e.g. RedHat 5+), look in /etc/nsswitch.conf, and
- if possible, disable the "nis" and "nisplus" options for "passwd", "shadow"
- and "group". This prevents unneeded runtime libraries being added into
- the vsftpd virtual memory space.
- 2) vsftpd will attempt to save CPU power by using sendfile() on capable
- operating systems. Currently, Linux 2.2+ and FreeBSD 3.0+ use sendfile().
- Consider running on these excellent operating systems.
- 3) Irritated by vsftpd using _two_ processes per connection? Don't be, it's
- a very secure architecture. However, if you run Linux 2.4+, or Linux 2.2.19+, a
- "one process" security model is possible thanks to nifty security features.
- See the vsftpd.conf man page.
- 4) Avoid large directories (e.g. thousands of entries) if possible. Many
- filesystems do not handle such cases efficiently at all. Preparing large
- directory listings will require vsftpd to use moderate amounts of memory
- and CPU. If you _must_ have large directories, consider either making them
- unreadable, or use a filesystem which copes well with large directories such
- as reiserfs.
