RAM cache

基本解釋

The problem with this approach is that you are actually reducing your available RAM cache, not increasing it.
這種方式的問(wèn)題是如果這麼做反而會(huì)減少可用的 RAM 緩存，而不是增加。
Memcached is an RAM cache for storing and handling data (which uses libevent at it's core, as well as being used with other libevent servers).
Memcached 是用於存儲(chǔ)和処理數(shù)據(jù)的 RAM 緩存（其核心使用 libevent，也可以使用其他 libevent 服務(wù)器）。
If you have multiple machines, the temptation is to set up a memcached instance on all of your spare machines to provide a massive amount of networked RAM cache storage.
如果有多臺(tái)機(jī)器，那麼很自然地會(huì)想要在所有多餘機(jī)器上設(shè)置一個(gè) memcached 的實(shí)例來(lái)提供一個(gè)超大的聯(lián)網(wǎng) RAM 緩存存儲(chǔ)。

There is no Level 3 cache, RAM maxes out at 640 MB and there is no support for ADC or DVI monitors.
