虽然JIT编译为加快执行提供了一些优势，但是这是以巨大的内存为代价进行的。
Although JIT compilation provides some advantages for speeding up execution, it does so at the cost of larger amounts of memory.
尽管通过JIT编译保持了平台无关性，但是付出了一定代价。
Although platform neutrality is maintained with JIT compilation, it comes at a price.
XCache将避免代价高昂且(严格来说)不必要的花费来重新编译相同的PHP代码去交付一个页面。
XCache avoids the costly and (strictly) unnecessary expense of recompiling the same PHP code to deliver a page.
在具有活动JIT编译器的JVM中，会通过不断编译编译代码的“边缘部分”，直到转换次数不会影响性能为止，最终消除这种代价。
In a JVM with an active JIT compiler, this cost is eventually eliminated by compiling "around the edges" of the compiled code until the number of transitions is too small to impact performance.
G77在灵活性和可移植性方面占优，但却以性能为代价，所以良好调优的商业编译器的市场依旧会很繁荣。
G77 excels in flexibility and portability at the expense of performance, so there's still a thriving market in well-tuned commercial compilers.
为了消除解释的高性能代价，JIT编译器选择将频繁执行的代码直接转换为CPU的本地指令。
To eliminate interpretation's high performance cost, a JIT compiler selects frequently executed code to be translated directly to the CPU's native instructions.
由于索引寄存器是用于访问结构，对一个编译器它们就像金子-更多的它们是一件好事，并且值得几乎任何代价来获得多个它们。
Since index registers are used for structure access, to a compiler they're like gold - more of them is a good thing, and it's worth almost any amount of effort to gain more of them.
如果您想多次重复发出同一条语句，那么odbc_exec函数是一种代价高昂的方法，因为它每次都要编译并执行该语句。
If you want to reissue the same statement multiple times, the odbc_exec function is an expensive approach because it prepares and executes the statement every time.
编译器优先泄漏最不频繁使用的变量，将泄漏的代价降到最低。
The compiler spills the least frequently used variables first, so as to minimize the cost of spilling. Spilling of variables can be avoided by.
这个假定，虽然对编译器最优化使用的各种静态分析来说是安全的，但是由于增加了时间和空间的代价，会致反病毒技术于不利处境。
This assumption, though safe for various static analyses for compiler optimizations, could spell doom for an anti-virus technology by increasing the time and space costs of the analyses.
虽然HP - TBTC结构是以牺牲一定的硬件资源为代价换取编译码的并行处理，但它可以成倍地提高编译码处理速度。
HP-TBTC can be implemented in parallel to obtain much higher encoding and decoding speed at the cost of more hardware resource.
虽然HP - TBTC结构是以牺牲一定的硬件资源为代价换取编译码的并行处理，但它可以成倍地提高编译码处理速度。
HP-TBTC can be implemented in parallel to obtain much higher encoding and decoding speed at the cost of more hardware resource.
