-# The SYMBOL_CACHE_SIZE determines the size of the internal cache use to

-# When the cache is full, less often used symbols will be written to disk.

-# If the system has enough physical memory increasing the cache will improve the
-# performance by keeping more symbols in memory. Note that the value works on
-# a logarithmic scale so increasing the size by one will roughly double the
