In addition to what Bruce mentioned I'd also suggest checking what version of SMB the mac is trying to use - if it's an older version, it will tend to be slower. If i instead try to use ftp then download from the server is very fast indeed and upload very good also.Īll firewall rules for the smb/afp traffic has no IPS/AV or other inspection enabled.Īny good clues why i see so bad file performance from Ventura and normal speeds with everyting else (http/https/ftp)? I have ExtremZ-IP installed on the file servers and even with AFP it is the same slow transfers. With Wireshark from the Mac, i see a ton of TCP retransmission and duplicates when the file copy starts, but all SMB2 communication right before seems to be normal without issues. Disabled ipv6, disabled wifi to make sure only wired lan was active. Tried setting the MTU sixe to 1280, 14, same same. I have tried different settings in /etc/nf without any luck or difference at all. Infact so slow FINDER most of the time halts or stops responding for a long time.ĭownloading 10GB file takes over 2 hours where it takes a very short time on a Windows machine. All Windows clients has a very good and stable smb2/3 connection to our Windows 2019 fileservers where upload/download speeds is around 3-4-5-600Mbit/s all depending on file size and numbers.īut we have a few Mac OS Ventura 13.2 and after moving the file servers from local lan to remote brach the file upload/download speeds is extremly slow. This weekend we moved our last onsite servers (VMs) to our datacenter. No issues with the vpn, it has been stable for a long time. I have a branch office vpn, ikev2, connection from a M370 (1Gbit connection) to a FireboxV (10Gbit connection). This might not be directly related Watchguard but here it goes.
