New Configuration Parameters

There are three new configuration parameters. Some of these can be set depending on the amount of RAM your node has and make it run faster if you have enough RAM.

Two parameters affect garbage collection:

gc_space_overhead (default 80) and gc_stack_limit (default 104876)

With, say, 4GB of RAM it is probably safe to set gc_space_overhead to a higher number like 160 (or maybe higher). With a lot of RAM you might try a value like 1000. Of course, if your memory is limited, you can also set it lower than 80.

One parameter affects the caches for the database:

db_max_in_cache (default 100000)

It does not seem like setting this to a high number like 100000 needs too much RAM, but if it eventually does start needing too much RAM, the parameter can be lowered. It can also be set even higher, of course.
