Hi,
I made a quick first test running the new version on an GB Ethernet link. I
just copy a 1GByte file from my server to local /dev/null. While with
20050413-0433 I got
$ time bin/arch/xrdcp root://iwrcgtest.fzk.de//tmp/testfile.dat /dev/null
real 0m10.909s
user 0m1.150s
sys 0m0.720s
with the new version I get:
[schwicke@iwrcgop027:/home/schwicke/Progamming/xrootd]$ time bin/arch/xrdcp
root://iwrcgtest.fzk.de//tmp/testfile.dat /dev/null
[xrootd] Total 1024.00 MB |====================| 100.00 % [36.6 Mb/s]
real 0m29.377s
user 0m1.670s
sys 0m1.190s
Going to quiet mode does not help (my first thought since I work remotely):
$ time bin/arch/xrdcp -s root://iwrcgtest.fzk.de//tmp/testfile.dat /dev/null
real 0m28.147s
user 0m1.150s
sys 0m0.380s
The test is done on Sun V20z dual Opterons, both for server and client, using
the onboard GE link.
Did I miss something ?
Thank's,
Ulrich
