After the syncing the files from the SharePoint to windows explorer, When open any document from the explorer SharePoint location first things happen after double click on a file is it takes a min to 30 sec to initiate the download of a file and after it downloaded into the system locally it opens and when we save as the file and try to browse the location of a folder on the SharePoint drive, a dialog box opens and says "Connecting to the server for information" and it can take up to 1 min to 3 min and after that only the browse window opens. IT started recently only, previously it wasn't like that. IT happens in the Malaysia side of the SharePoint only, in our primary company Singapore it works smoothly, there is no dialog box open when we save as the file and downloading of the file also instant.
Troubleshoots i have tried:
1. Fully update the windows
2. MS Office 365 also up to date.
3. Windows image also fine no issues there as well.
4. Network speed also good 100 Mbps per system downloading and uploading.
Please help us on this, is there anything else we can do to make the performance better.
