Hi,

We are experiencing slowness when accessing webmail. There is no issue observed from the server side, as it appears to be running smoothly. However, from the SmarterMail logs, we found the following errors:

[2025.08.19] 00:04:23.183 [FileFunctions] File is over 15mb, this might cause reduced performance. Size: 16.5mb Filepath: F:\SmarterMail\Domains\se***\Users\ray\folder-80003.json

Could this be the root cause? Previously, we tried renaming the affected .json files, and performance improved temporarily, but the file sizes eventually exceeded 15MB again.

Do you have any suggestions to resolve this issue permanently? Would upgrading to the latest version help address this problem?

Thank you.
