- Plesk for Linux
When listing a directory with more than 20000 files in it via FTP, it takes more than 2 minutes to complete.
ProFTPd version 1.3.6 is installed:
# proftpd -v
ProFTPD Version 1.3.6
High CPU usage 100% maybe observed on the server.
This is a ProFTPd bug 4360: Slow listing for a directory with 20000 files.
The issue is also registered as a Plesk bug with ID PPPM-9486, which will be fixed in one of the future product updates.
Currently, there is no workaround.
