Rsync has been churning away for 45 mins, presumably bulding an in-core list of files to be copied to the destination. This is a very very large filesystem we are copying locally - approximately 4.2million files (WebCT). The resident process size for rsync has grown to 72Mb. - is this normal behaviour for a file system this size, and does rsync have the ability to handle such a large number of files? The filesystem size is relatively modest - 20gb. or so, but the millions of small files might explain while its taking so long.
I presume that once rsync has built it's in-memory list of files it proceeds to copy the whole shebang over. This is the initial copy, subsequent copies should be much faster.
Also, are there any options suitable for turning off that would speed up the whole process? We're using (as root)
# rsync -a --progress --stats /global/webct/ /target
Solaris 8 and rsync 2.5.7
Thanks
