Setting the Configuration Property
To configure the cache size, you can set the pcoip.image_cache_size_mb property. For example, the
following setting configures the cache size to be 50MB:
pcoip.image_cache_size_mb = 50
Use a space before and after the equals (=) sign.
If you specify a number less than 50, the number is converted to 50. With Horizon Client 3.1 and later, if you
specify a number that is less than the amount of available memory divided by 2, the cache is set using the
following formula, but the minimum is still 50:
customer-setting - 10
With Horizon Client 3.0, if you specify a number larger than the maximum, the number is converted to
1024MB. With Horizon Client 3.1 and later, if you specify a number that is larger than the available memory
divided by 2, the cache is set using the following formula:
available-memory / 2 - 10
You can set this property in any of several files. When Horizon Client starts up, the setting is processed from
various locations in the following order:
1 /etc/teradici/pcoip_admin_defaults.conf
2 ~/.pcoip.rc
3 /etc/teradici/pcoip_admin.conf
If a setting is defined in multiple locations, the value that is used is the value from the last file read.
NOTE You can set the following property to display a visual indication that the image cache is working:
pcoip.show_image_cache_hits = 1
With this configuration, for every tile (32 x 32 pixels) in an image that comes from the image cache, you can
see a rectangle around the tile.
