我可以将应用程序代码放在RAM中的分区上吗？

Question

我想使用RAM而不是SSD。我正在寻找有经验的人给我一些建议。我想挂载一个分区并将其放入我的Rails应用程序。

有什么想法吗？

UPD：我测试了SSD和RAM。我有一个OSX，4x4Gb金士顿@ 1333内存，英特尔酷睿i3 @ 2,8 Ghz，OCZ Vertex3 @ 120Gb，硬盘希捷ST3000DM001 @ 3Tb。我的操作系统安装在SSD和ruby上，宝石放在SSD的主文件夹中。我在sqlite中创建了包含10.000个产品项的新Rails应用程序，并使用代码创建控制器：

@products = Product.all
Rails.cache.clear

用AB测试。

所以，我认为在ruby中使用gems放置在SSD上并缓慢地获取这些脚本，我将在真实服务器上进行测试，并将所有ruby脚本放入具有更复杂代码或实际应用程序的RAM中。
