Can't disable disk caching

Hello, we have a Windows Server 2008 R2 terminal server with 60-70 active users on average. Recently we have disk I/O performance problems so we decided to disable disk cache in Firefox. So I set these options in mozilla.cfg:

browser.cache.disk.capacity 0

browser.cache.disk.enable false

browser.cache.disk.smart_size.enabled false

I checked about:config to make sure these options actually applied. However in Performance Monitor I can still see some firefox processes intensively using files in "<user_profile>\AppData\Local\Mozilla\Firefox\Profiles\<id>.default\cache2\entries\" folder. Is there a way I can completely disable disk cache?

OS: Windows Server 2008 R2 Enterprise SP1

Firefox version: 45.5.1 ESR

I think I resolved the issue after I manually deleted all files from cache2/entries directory. Here's about:cache output:

disk Number of entries: 1 Maximum storage size: 32768 KiB Storage in use: 0 KiB Storage disk location: none, only stored in memory

It seems that if there're cache files in cache folder Firefox reading them despite caching settings.
