FTP Server needed

I am looking for a good FTP server.

I was, previously, using !DeltaNet which I found to be very good. But it is not 32bit compliant.

I am currently trying FTPs – But it is very, very CPU hungry. !CPUload shows it as way over 50% when idle. The Pi stops when FTPs is tranfering a file.

This is no good when I when to use it in conjunction with other mult-tasking applications. Does anyone know of an alternative, please?

Even typing this with FTPs running gave numerous typos, which were not my fault.

EDIT: many hours later. I have now come to the conclusion that FTPs is causing more problems on the Pi than just high CPU usage. (The reason, perhaps, is that FTPs does not cope with the well known USB problem on the Pi Hardware/Firmware). Either way, it has been consigned to the “Recycle Bin”, whilst I look for an alternative.
