VERY VERY slow file copy

[boed1]

Hello,

I'm getting very slow file transfers between my two network computers. I'm running Free File Sync 5.16 on Windows 8. If I manually select a file to copy it copies at about 60MBs. If I use freefilesync it copies at about 6MBs. I've tested on different drives and double checked the numbers in task manager network throughput. So to be clear, my network performance is fine with a normal copy and paste in both directions between computers but very slow with free file sync. I love all the features of freefilesync but I'm not sure why it is so slow.

I've noticed if I disable Symantec and reenable it, it helps but I'm curious if it uses some unusual port since this didn't happen until the past few days.

I'm having the same problem. I'm copying files from a Window 7 laptop to a CIF on a FreeNAS NAS. Copying about 200GB of data I'm getting about 100KB/sec!!! Sometimes less, like now where it's copying at 50KB/sec. If I copy a large file to the same location on the NAS I'm getting about 25 MB/sec so it must be something to do with FreeFileSync.

FFS delegates the responsibility of file copying to Windows by calling the Win32 API function CopyFileEx. So whatever is causing the slowdown, it's highly unlikely that it's caused by FFS. I would start looking for general network issues, or maybe even hardware issues.
