#UseFileSystemCache = true
# ----------------------------
# File system cache threshold
#
# The threshold value that determines if Firebird will use the file system
# cache. File system caching is used if database cache size in pages
# (configured explicitly in the database header or via DefaultDbCachePages setting)
# is less than the value of FileSystemCacheThreshold.
#
# To always use the file system cache, set FileSystemCacheThreshold to a large value.
# To bypass the file system cache for all databases, set FileSystemCacheThreshold to
# zero.
#
# CAUTION!
# This setting is deprecated and will be removed in future Firebird versions.
# Consider using UseFileSystemCache setting instead.
# If UseFileSystemCache is set, the value of FileSystemCacheThreshold is ignored.
# If UseFileSystemCache is not set, and FileSystemCacheThreshold is set, the value
# of FileSystemCacheThreshold is in use and accounted by the engine.
#
# Type: integer, measured in database pages
#
# Per-database configurable.
#
#FileSystemCacheThreshold = 64K
# ----------------------------
# File system cache size
