But as with all benchmark >programs, know and understand the big * next to them. I'm curious. I looked at bonnie, and it creates a huge file (with (2**31)-1 problems), which it then reads and re-writes with multiple child processes (unless I misunderstand the man page). However, this exercises the buffer cache but does not exercise the creation of lots of small files, directories and subdirectories, etc... (e.g., the kind of traffic that one might see with a heavily loaded news server), and this misses much of the potential performance enhancements of "soft updates", etc.... I'm wondering if anyone has heard of any benchmark programs that are more oriented towards some sort of simulation of a heavily loaded news server, or the kind of load you might see with a heavily loaded anonymous ftp server (both during the mirror updates and during heavy reader load)? Are any of these benchmarks portable to other platforms? -- These are my opinions -- not to be taken as official Skynet policy ____________________________________________________________________ |o| Brad Knowles, Belgacom Skynet NV/SA |o| |o| Systems Architect, News/mail/FTP Admin Rue Col.
