https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=253274 Bug ID: 253274 Summary: When using sftp to transfer files, there are severe performance loss and high CPU usage. Product: Base System Version: 12.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: number201724@me.com Created attachment 222187 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=222187&action=edit screenshot When I use sftp to transfer a close to 30GB to freebsd, sftp, sshd and kernel seem to occupy a very high CPU, and the transfer speed is slow. And the speed is only about 50MByte/s. At the same time, I transfer files to Linux under the same network environment, and it has a speed of more than 100MByte/s. And the cpu usage is low.
