Transfer speed is slow when using TLS

[sch]

When using TLS, transfer speed is slow (around 100KB/s)

I have tried use client version 3.9.0 and 3.9.0.2, server is FileZilla Server 0.9.45.
During transferring, CPU usage is <10% (2.6Ghz).

But FileZilla client in a Windows PC works fine when connect to the same server, the speed is > 1MB/s.

Okay, I don't get it. I can guess:

You have three computers on the same network:

• A Windows computer where you run FileZilla Server.
• A Mac OS X computer, where you run FileZilla Client.
• Another Windows computer, where you run FileZilla Client.

Downloading files from the FileZilla Server via the other Windows computer is fast, whereas downloading the same files from your OS X computer is slow?

The computers are on different network.

• A Windows computer run FileZilla Server.
• A MacBook, run FileZilla Client (both OS X and Windows)

-> When using TLS, transfer speed is slow.

• Another Windows computer, run FileZilla Client.

-> Everything is fine.

Downloading files from the FileZilla Server via the other Windows computer is fast, whereas downloading the same files from MacBook is slow.

But that's not a problem of FileZilla then.

If you can dual-boot your MacBook to run OS X and Windows, and FileZilla on OS X and Windows there is slow, while it is fast on your other Windows computer, it is a problem of your MacBook. Maybe you use wireless instead of wired connectivity?

Anyway, not a bug with FileZilla.
