I run hugo server for previewing my site locally with this PowerShell script:
[console]::WindowWidth=120
[console]::WindowHeight=30
[console]::BufferWidth=[console]::WindowWidth
$host.ui.RawUI.WindowTitle = "Test Server"
Set-Location -LiteralPath (Split-Path -Parent (Split-Path -Parent $MyInvocation.MyCommand.Path))
Remove-Item "public" -Recurse -ErrorAction "Ignore"
Remove-Item "resources" -Recurse -ErrorAction "Ignore"
# Fast Render: Home page + Content page last edited (if any) + Content page last visited (up to 10)
hugo server ārenderToMemory --printMemoryUsage --disableFastRender -D -p 80
But site rebuilding takes too much time, especially if only few words has been changed in single file.

As you can see, initial site building time is not that bad (around 30 seconds), but site rebuilding takes too much time (more than 60 seconds), even if all Iāve changed is just a word in single file.
I also tested if removing --disableFastRender would speed up rebuild process, but that didnāt change anything. Site rebuilding still takes long time, more than 60 seconds.
Since both Hugo executable and site source is on SSD, I donāt think it is related to slow I/O.
Here is what hugo --templateMetrics --templateMetricsHints shows. I posted it in separate site because it is too long.
This is what hugo env says.
hugo v0.125.7-b1d808bc373f53ad37c8966bb02a6aea095db5f8+extended windows/amd64 BuildDate=2024-05-08T14:46:24Z VendorInfo=gohugoio

What can be the reason of this slow site rebuild? How can I solve it?
PS. Iāve set my site source repository as private. If you need anything about my siteās source, please tell me.
