If the performance of your Filezilla is sluggish, getting timeouts, or tired of the pausing due to file exist issues, try the following tips:
set transfers options
– open FileZilla
– on the top menu, select edit
– click on transfers
– set maximum simultaneous connections to 5
You can try 10, but if you have a lot of LARGE files,
too many can cause timeouts.
Set file exists action
– Under transfers on the left navigational pane:
click the file exists action link
– change “Uploads” to the following selection:
overwrite the file if size differs or the source is newer
Those are two very quick options you can try. Also, make sure you have the latest FileZilla. Click help, then check for updates.
