The Pre Plus has 512 MB of memory and thus runs 2.1 quite well, but this is not the case with the original Pre since it has only 256 MB. Luckily, Palm adopted WebOS Internals's configuration of the standard Linux compcache technology that was ported to the custom kernels, and it comes active, but with only 10 MB. One potential way to enhance performance in original Pre devices is to make the compcache bigger. d+ n8 L3 s, G( Q
3P有512M内存，所以用2.1相当不错，但只有256M内存的2P就比较差。而PALM实际上使用了WebOS Internals在超频核心中加入的COMPCACHE技术，但只有10M。一个可能有效的方法就是让这个值更大一些。" j8 y9 ~6 F/ E2 p$ L9 o p9 J/ x

使用新的Govnah application（7.25）来提高，先取消它，然后可以修改大小，然后再度启用它，不过这个办法一重启就没用了。
