Large family tree data files, what to do, and what not to do.

For small filesInitial import of a large (100, you 000+) database from either Gramps XML formats or GEDCOM is can work on GEDCOM or GRAMPS XML formattake a few hours. This works greatYou will need to adjust thenumber of allowable locks.For 140,000 people you should use: * ''max_locks'' 300000* ''max_objects'' 300000

However, these formats are completely loaded in your computer memory so, for larger files, The easiest way to do this becomes slow and might bring your computer is to:# create a new Family Tree# exit Gramps# add a '''<code>DB_CONFIG</code>''' file to the database directory before importing (see '''<code>gramps -l</code>''' output for the directory of a standstillspecific family tree.)

Therefore, you should only handle large files by using the GRAMPS GRDB format. You do Contents of this by creating a new GRDB DB_CONFIG file and importing the large file into it. This can take a long time, so do it in the evenings! If you '''enable database transactions''' in the should be: #may want to fiddle with cachesize also {{man menu|Edit->Preferences->General}} menu tab, the importing of data will then be much faster.#set_cachesize 0 200000000 2 set_lk_max_locks 300000Also if you have a file that large it might be prudent to break up file into smaller pieces (i.e. Maternal & Paternal lines in different files, if they are not interrelated) so you only have to use a smaller file. set_lk_max_objects 300000

As there are many people, loading the person view might take some time. See a comparison of [[GRAMPS Gramps Performance|performance]] on large datasets, between different GRAMPS Gramps versions.

You can circumvent this load time by going to the [[Gramps Relationships Category view screenshot|relationships view]] before opening the grdb filefamily tree. This will open the active person and their family extremely fast, independent of the amount of data you gathered.

* click on a person in the [[Gramps People screenshotCategory screenshots|people view]]. Now start typing the family name of the person you need. The view will automatically go to the family name as you complete your typing.
