    I recently upgraded to Tomato from ASUSWRT Merlin.

    I've got an Original Xbox I use as a gaming/media box and was FTPing on my LAN between my computer through the RT-AC68U to the Xbox using FileZilla at ~11MB/s. Xbox has a 100M connection. Everything is hardwired and using Cat6.

    After installing FreshTomato 2019.1.015-beta, FTP speeds have slowed to ~2-4MB/s. I am totally lost as to why I'm getting the slowdown and have searched high and low for an answer in these forums and on the internet.

    The slower speeds should have zero to do with the hardware, unless this is a chipset limitation in the router itself and in Tomato.

    If anyone has insight, I'd appreciate it.

    I am building stable 2018.5. Everything is OK. I'm transferring 3GB in 2 minutes. Make sure Bandwidth Limiter and QOS are disabled. Wireless WMM must be enabled.

    Thanks @rgnldo ... This isn't over WAN or internet. This is LAN... though the router may be treating it like WAN because it's over FTP? I'm not a networking expert.

    Bandwidth Limiter and QoS are disabled. WMM is enabled

    Advanced > Miscellaneous: CTF is on. That was one of the first things I turned on after flashing Tomato.

    Currently getting 125Mbits/s down with CTF on. But, CTF doesn't appear to affect anything of LAN.

    Correct, CTF only affects WAN traffic. I would suggest trying an ftp transfer from/to the router itself, as well as a different LAN client. Try another protocol transfer as well, such as SMB. See what speeds are obtained from a variety of tests.
