# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with

我已经my.cnf尽可能地调整了我的方法，但 MariaDB 仍然疯狂地飙升 - 可以在几秒钟内从 110% 上升到 200+。我已经尽我所知为我的表格建立了索引，但似乎没有什么能平息滞后。有没有办法，因为我有 80GB 的 RAM，我可以让 MariaDB 使用更多的 RAM，因为目前它只使用了 80GB 总量的 9% 左右？

我在这里感到迷失，因为我所做的一切都不起作用，甚至似乎没有帮助。
