This may be > platform-specific. Anyway, this shows up on Windows NT as well. I'm pretty sure Nagle's algorithm is the default for all implementations of TCP/IP purely because of the overhead associated with the various packet headers etc. i.e. be careful with the TCP_NODELAY flag. Interesting to know how much data exactly was used in the benchmarks, and whether 5 samples are enough statistically speaking. ********************************************************************** Joe Shevland - Horizon Technologies International Email: joe.shevland@horizonti.com We are all in the gutter, but some of us are looking at the stars - Oscar Wilde ********************************************************************** To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-java" in the body of the message
