- # cycle:
- #
- # This is the quantum of time for preload. Preload performs
- # data gathering and predictions every cycle. Use an even
- # number.

- # Note: Setting this parameter too low will may reduce the
- # system performance and stability.
- #
- # unit: seconds
- # default: 20

- # usecorrelation:
- #
- # Whether correlation coefficient should be used in the prediction
- # algorithm. There are arguments both for and against using it.
- # Currently it's believed that using it results in more accurate
- # prediction. The option may be removed in the future.
- #
- # default: true
- usecorrelation = true
- # minsize:
- #
- # Minimum sum of the length of maps of the process for
- # preload to consider tracking the application.
- #
- # Note: Setting this parameter too high will make preload less
- # effective, while setting it too low will make it eat
- # quadratically more resources, as it tracks more processes.

- # The following control how much memory preload is allowed to use
- # for preloading in each cycle. All values are percentages and are
- # clamped to -100 to 100.
- #
- # The total memory preload uses for prefetching is then computed using
- # the following formulae:
- #
- # max (0, TOTAL * memtotal + FREE * memfree) + CHACED * memcached
- # where TOTAL, FREE, and CACHED are the respective values read at
- # runtime from /proc/meminfo.
- #
- # memtotal: precentage of total memory
- #
- # unit: signed_integer_percent
- # default: -10
- #
- memtotal = -10
- # memfree: precentage of free memory
- #
- # unit: signed_integer_percent

- # doscan:
- #
- # Whether preload should monitor running processes and update its
- # model state. Normally you do want that, that's all preload is
- # about, but you may temporarily want to turn it off for various
- # reasons like testing and only make predictions. Note that if
- # scanning is off, predictions are made based on whatever processes
- # have been running when preload started and the list of running
- # processes is not updated at all.
- #
- # default: true
- doscan = true
- # dopredict:
- #
- # Whether preload should make prediction and prefetch anything off
- # the disk. Quite like doscan, you normally want that, that's the
- # other half of what preload is about, but you may temporarily want
- # to turn it off, to only train the model for example. Note that
- # this allows you to turn scan/predict or or off on the fly, by
- # modifying the config file and signalling the daemon.
- #
- # default: true
- dopredict = true
- # autosave:
- #
- # Preload will automatically save the state to disk every
- # autosave period. This is only relevant if doscan is set to true.
- # Note that some janitory work on the model, like removing entries
- # for files that no longer exist happen at state save time. So,
- # turning off autosave completely is not advised.
- #
- # unit: seconds
- # default: 3600

- autosave = 3600
- # mapprefix:
- #
- # A list of path prefixes that controll which mapped file are to
- # be considered by preload and which not. The list items are
- # separated by semicolons. Matching will be stopped as soon as
- # the first item is matched. For each item, if item appears at
- # the beginning of the path of the file, then a match occurs, and
- # the file is accepted. If on the other hand, the item has a
- # exclamation mark as its first character, then the rest of the
- # item is considered, and if a match happens, the file is rejected.
- # For example a value of !/lib/modules;/ means that every file other
- # than those in /lib/modules should be accepted. In this case, the
- # trailing item can be removed, since if no match occurs, the file is
- # accepted. It's advised to make sure /dev is rejected, since
- # preload doesn't special-handle device files internally.
- #
- # default: (empty list, accept all)
- mapprefix = /usr;/lib;!/
- # exeprefix:
- #
- # The syntax for this is exactly the same as for mapprefix. The only
- # difference is that this is used to accept or reject binary exectuable
- # files instead of maps.

- # default: (empty list, accept all)
