it takes time to open files after clicking search result(filesystem)

(from github.com/hillxrem)
When I use FESS for my laptop , just about 1sec is needed to open files after
clicking search result , but for a fileserver(contains >200,000 files), it takes about 10-15sec to open.(after clicking link like this <http://FESSserver/go?rt=1234567890&docld=12345678abcde… >)
Is there any way to speedup this thing ?
I can open files as admin from system information page quickly by clicking link like <<file:/fileserver/file…>>
, but I want to share FESS with other people.

Is your PC spec good enough?
It’s better to check fess.log by debug level.

Content Proxy is a feature to proxy a file access by Fess and is enabled by default.
To disable it, set search.file.proxy to false in system.properties:

search.file.proxy=false

However, you may not be able to open files from file://... for a browser security policy.
It’s not a problem on Fess…

Thank you @marevol , and I’ve added <search.file.proxy=false> to ./etc/fess/system.properties. But , in search result page, FESS(12.1.2 ,dockerCE18.03.1 on CentOS7) links files still like <http://FESSserver/go?rt=...> and redirects to <smb://fileserver/????????/???????>.
“???/???” is literally “???/???” in my browser ,and probably it is originally a filename or foldername spelled in Chinese character.(Of course , this link doesn’t work.)
Is there any properties to be set in order to use <<file://>> in search result ?

And I’ve also checked fess.log and found a process in trouble like this.(Before adding search.file.proxy=false)

Any user of CentOS( runs FESS) can’t access our fileserver without some specific username(domain user) and password , and these are set in filecrawl in FESS(username differs in each filecrawl). Is this the reason for this matter? If so , why can I open files finally…?
