To: hackers@freebsd.org Date: Tue, 17 Dec 1996 19:07:56 +0100 (MET) X-Mailer: ELM [version 2.4 PL23] Content-Type: text Sender: owner-hackers@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Just a curiosity. I just ran mkisofs on a partition mounted over NFS using TCP. Since my kernel logs dup traffic per connection, on the server I noticed this: == dup:rx 136:47615878 dup:tx 37052:615632570 == 131.114.9.236:2049 131.114.83.21:1025 i.e. 587MB out, 45MB in (this is TCP payload, excluding headers). Kind of surprising that 8% of input data, considering that the partition is readonly! There seems to be an explaination -- many files in that partition were small ones.
