Performance

• The custom SMBJ and WebDAV clients achieve 1 Gbps network speeds over Wi-Fi 7, so after v1.11.x the image reader defaults to have image caching disabled.
• Windows 11 JXR HDR screenshots can be displayed directly in fp16 bitmaps without tone mapping, or transcode to Ultra HDR Jpeg. The prefetch and decode ahead is set to 1 for JXR format to avoid OOM crashed.
• The image loader was tweaked for preloading and decoding 20MB jpg files without any OOM crashes, and smaller files should load instantly.
• Accurate HDR presentation of RAW and JXR images (compared with DaVinci Resolve).

To use WebDAV

openssl req -x509 -newkey rsa:4096 -keyout server.key -out server.crt -days 365 -nodes
.\rclone.exe serve webdav "D:\" --addr :8443 --cert .\server.crt --key .\server.key --read-only --user admin --pass password

To use SMB3 encryption:

Get-SmbShare | Select-Object Name, EncryptData
Set-SmbShare -Name "Media" -EncryptData $true
Set-SmbServerConfiguration -RejectUnencryptedAccess $false -Force

while ($true) {
    Clear-Host
    $config = Get-SmbServerConfiguration
    $sessions = Get-SmbSession

    Write-Host "--- SMB SERVER ENCRYPTION STATUS ---" -ForegroundColor Cyan
    Write-Host "Global Server Encryption Enabled : $($config.EncryptData)"
    Write-Host "Reject Unencrypted Access       : $($config.RejectUnencryptedAccess)"
    Write-Host "Active Sessions                 : $(($sessions).Count)"
    Write-Host "Timestamp                       : $(Get-Date -Format 'HH:mm:ss')"
    Write-Host "------------------------------------`n"

    if ($sessions) {
        $sessions | Select-Object ClientComputerName, ClientUserName, Dialect, NumOpens | Format-Table -AutoSize
    }

    Start-Sleep -Seconds 1
}
