i just run very simple test. 1GB network, 500 MB test file on web server
and wget from centos 6 and freebsd 8.3 vm's, both with virtio.
wget -nd --no-proxy http://server/test -O /dev/null
result is the same:
Length: 524288000 (500M) [application/octet-stream]
Saving to: `/dev/null'
100%[====================>] 524,288,000 112M/s in 4.5s
then i try freebsd with fetch
freebsd8:~% fetch -o /dev/null -d http://server/test
/dev/null 100% of 500 MB 41 MBps 00m00s
fetch is 2.5x slower. that's interesting. i don't know what's the
difference between fetch and wget but i'll try to found out.
