performance with >50GB files

[René Rebe]

Hi all,

today we had a performance issue transfering a big amount of data where
one file was over 50GB. Rsync was tunneled over SSH and we expected the data 
to be synced within hours. However after over 10 hours the data is still not 
synced ... The sending box has rsync running with 60-80 % CPU load (2GHz
Pentium 4) while the receiver is nearly idle.

So far I had no acces to the poblematic setup but I will have to analyze this
soon. I would like to ask beforehand if there are known performance hits
syncing such huge files?

Sincerely,
  René Rebe
