This article applies to all MetaDefender ICAP Server releases deployed on both Windows & Linux systems.

In order to improve the file scan speed, a custom tempdirectory can be set for the Metadefender ICAP Server.

Step 1:

Create a RAMDISK on your system.

We recommend the following tool for this: Tools and utilities for Windows

After installation, use the ImDisk Virtual Disk Driver application to create a new RAMDISK.

The changes to take effect restart the mdicapsrv service.

After the service restart, your custom directory will be used for temporary file storage during file scan.

2. Instructions for Linux:

# Add this line at the end of the file tmpfs /mnt/ramdisk tmpfs size=5G,uid=1000,gid=1000,mode=0755 0 0

Step 2: Mount this directory

sudo mount -a

Step 3: Validate the directory

sudo df -h /mnt/ramdisk

Please note that the mdicapsrv service can write to this directory.

Step 4: Update the config file /etc/mdicapsrv/mdicapsrc.conf

[global] dbmode=1 icapaddress=0.0.0.0 icapport=1344 icaps_port=11344 restaddress=* restport=8048 webhook_address=0.0.0.0 tempdirectory=/mnt/ramdisk [logger] logfile=/var/log/mdicapsrv/mdicapsrv.log loglevel=info nginx_logfile=/var/log/mdicapsrv/nginx-mdicapsrv.log
