Opening MS project files are slow on IPsec with SMB sharing permissions set to Everyone Full Control Access
Hi Guys, I am working on a new file shares on our Brand new file 2025 server, having some performance issues when opening MS project files from a win11 computer on a remote office. Remote offices are connected with our AutoVPN IPsec tunnels. Network latency is around 34Ms..As tested, there is no network performance issue..
So, Long story short, when I configure SMB share permission as Everyone read only access for the file shares, the speed of opening project files is good. Takes about 5-7 seconds... Seems copying files directly is also good via SMB from a remote office...however once I set smb permission to everyone full Control or give Change rights, the performance of opening project files is degraded, opening the same Ms project file can take 30 seconds....I know the Ms project needs to have autosave etc can showhow affect performance..I wouldn't thought it degraded this much?
Tried SMB compressor didn't help with opening the project file..
Also, I noticed the performance was fine in the beginning after I created SMb share, after for sometimes, it is getting slow...I feel like there are some weird SMB caching somehow affect this performance....on the file shares, I already set no file caching under Advanced sharing options..
Any tips you can possibly share that I could give a try?
