Bug ID: 13609 Summary: rsync can be crazy slow on os x 10.13.6 when copying via usb drives Product: rsync Version: 3.1.3 Hardware: All OS: All Status: NEW Severity: normal Priority: P5 Component: core Assignee: way...@samba.org Reporter: mvola...@aecom.yu.edu QA Contact: rsync...@samba.org I am copying files from one USB SATA drive to another connected to a Mac Pro via USB 3. Rsync should be able to copy approaching 100 MB/second, but it never copies anywhere near this speed and for a few files, it's so slow as to almost be stalled, averaging near 131KB/second. The OS is Mac OS 10.13.6 and the rsync is provided via homebrew. The command being used is as follows /usr/local/bin/rsync --acls --archive --delete --exclude-from=/usr/local/etc/backupignore --sparse --verbose --progress --xattrs /Volumes/externalhd/ /Volumes/backuphd/external/ -- You are receiving this mail because: You are the QA Contact for the bug. -- Please use reply-all for most replies to avoid omitting the mailing list.
