Details:
The performance of the copy implementation with the new client is ~ 25%
slower. This is easily reproduceable and the results are stable:
[root@eosdevsrv1 build]# time xrdcp -np root://localhost//eos/dev/2rep/1G - >
/dev/null
real 0m8.955s
user 0m0.556s
sys 0m1.504s
[root@eosdevsrv1 build]# time xrdcopy --nopbar
root://localhost//eos/dev/2rep/1G - > /dev/null
real 0m11.046s
user 0m0.893s
sys 0m1.164s
( file is always cached on server side and server is exclusive to the client
).
We see similar performance degradation when using the XrdCl classes
directly.
