I have a method that looks like this
public Dao<ModelStore, Integer> getDaoStore() throws SQLException {
return BaseDaoImpl.createDao(getConnectionSource(), ModelStore.class);
}
when i call getDaoStore
it is quite a lengthy process. In my log's i can see that the GC runs after every call to this, so I'm guessing there's a lot going on with this call.
Is there a way to speed this up?
A deep examination of Android-land has revealed that because of a gross
Method.equals()
method, annotations under Android are very slow and extremely GC intensive. We added table configuration files in version 4.26 that bypass this and make ORMLite start much, much faster. See this question and this thread on the mailing list.We continue to improve annotation speeds. See also: ORMLite poor performance on Android?
DAO creation is a relatively expensive process. ORMLite creates a data representation of both the class and the fields in the class and builds a number of other utility classes that help with the various DAO functionality. You should make sure that you call the
createDao
method once per invocation. I assume this is under Android @Pzanno?In 4.16 we added a
DaoManager
whose job it is to cache the Dao classes and this was improved in version 4.20. You should then always use it to create your Daos. Something like the following code is recommended:Hope this helps. A memory audit of ORMLite is probably also in order. It's been a while since I looked at it's consumption.
