Hi, TRY
Endian moved from Dansguardian to C-ICAP from version 3.0. In order to improve performance you need to edit a settings file from the cli.
#nano /usr/lib/efw/icap/default/settings
It shows the following:
MAX_SERVERS=3
THREADS_PER_CHILD=10
Which are pretty low for a lot of users or high speed bandwidth.
Change the settings to:
MAX_SERVERS=10
THREADS_PER_CHILD=50
Save and exit the file and reboot or restart the C-ICAP service.
Improved speed with your settings, thanks!
