Different FTP threads for scanning / transfer?

[nmkaufman]

Is it possible to set a different number of FTP threads for scanning vs. the actual transfer of files?

I use 30 threads to scan folders on my FTP server, but obviously things get hairy if I try and transfer 30 files at the same time. I only have ~20mbps internet.

I'd like to continue to scan my folders with 30 threads, but transfer using only 2.

I've been manually changing the number of threads back and forth, but is there an easier way?

Thanks in advance.

Technically, reading an FTP directory's content is the same as downloading a small file. So I'm not sure if it would be justified to make the parallel operations setting more fine-granular.

I'm the same guy who had the question about detecting moved / renamed files over FTP.

Maybe the solution to both of my problems is just to use a VPN, and sync my files over NFS / SMB.
