It operates by intercepting system calls, or requests from the software to the operating system, and translating them from <trademark class="registered">Windows</trademark> calls to calls that FreeBSD understands. It will also translate any responses as needed into what the <trademark class="registered">Windows</trademark> software is expecting. So in some ways, it <emphasis>emulates</emphasis> a <trademark class="registered">Windows</trademark> environment, in that it provides many of the resources <trademark class="registered">Windows</trademark> applications are expecting.
它的工作方式是拦截系统调用, 或从软件到操作系统的请求, 并将它们从 <trademark class="registered">Windows</trademark> 的调用翻译成 FreeBSD 能理解的调用。它还会根据需要将任何响应翻译成 <trademark class="registered">Windows</trademark> 软件所期望的内容。因此在某些方面,它<emphasis>模拟了</emphasis><trademark class="registered">Windows</trademark>环境,因为它提供了许多<trademark class="registered">Windows</trademark>应用程序所期望的资源。

However, <application>winecfg</application> makes it possible specify overrides for the built-in libraries, particularly there is a version of <trademark class="registered">Windows</trademark> available on the same machine as the host FreeBSD installation. For each library to be overridden, do the following:
然而,<application>winecfg</application>使得指定覆盖内置库成为可能,特别是在与FreeBSD安装相同的机器上有一个<trademark class="registered">Windows</trademark>的版本。对于每个要被覆盖的库,请执行以下操作

If ZFS is not able to allocate the required memory to compress a block with <acronym>Zstd</acronym>, it will fall back to storing the block uncompressed. This is unlikely to happen outside of the highest levels of <acronym>Zstd</acronym> on systems that are memory constrained. The sysctl <literal>kstat.zfs.misc.zstd.compress_alloc_fail</literal> counts how many times this has occurred since the <acronym>ZFS</acronym> module was loaded.
如果ZFS无法分配所需的内存来使用<acronym>Zstd</acronym>压缩一个块,它将回到未压缩的块存储。在内存有限的系统中,除了最高级别的<acronym>Zstd</acronym>之外,这种情况不太可能发生。sysctl <literal>kstat.zfs.misc.zstd.compress_alloc_fail</literal>会统计自<acronym>ZFS</acronym>模块被加载以来发生了多少次。

<acronym>ZFS</acronym> offers 19 levels of <acronym>Zstd</acronym> compression, each offering incrementally more space savings in exchange for slower compression. The default level is <literal>zstd-3</literal> and offers greater compression than <acronym>LZ4</acronym> without being significantly slower. Levels above 10 require significant amounts of memory to compress each block, so they are discouraged on systems with less than 16 GB of <acronym>RAM</acronym>. <acronym>ZFS</acronym> also implements a selection of the <acronym>Zstd</acronym> <emphasis>fast</emphasis> levels, which get correspondingly faster but offer lower compression ratios. <acronym>ZFS</acronym> supports <literal>zstd-fast-1</literal> through <literal>zstd-fast-10</literal>, <literal>zstd-fast-20</literal> through <literal>zstd-fast-100</literal> in increments of 10, and finally <literal>zstd-fast-500</literal> and <literal>zstd-fast-1000</literal> which provide minimal compression, but offer very high performance.
<acronym>ZFS</acronym>提供了19个<acronym>Zstd</acronym>压缩级别,每个级别的压缩速度较慢,但却能逐步节省更多的空间。默认级别是<literal>zstd-3</literal>,提供比<acronym>LZ4</acronym>更大的压缩率,但速度却不会明显变慢。超过10的级别需要大量的内存来压缩每个区块,因此在<acronym>RAM</acronym>小于16 GB的系统上不推荐使用。<acronym>ZFS</acronym>还实现了<acronym>Zstd</acronym> <emphasis>fast</emphasis>级别的选择,这些级别的速度会相应变快,但提供的压缩比较低。<acronym>ZFS</acronym>支持<literal>zstd-fast-1</literal>到<literal>zstd-fast-10</literal>、<literal>zstd-fast-20</literal>到<literal>zstd-fast-100</literal>,增量为10。最后是<literal>zstd-fast-500</literal>和<literal>zstd-fast-1000</literal>,它们提供最小的压缩量,但速度快。

Even when data is updated frequently, there are often performance gains that come from enabling compression. One of the biggest advantages comes from the compressed ARC feature. <acronym>ZFS</acronym>'s Adaptive Replacement Cache (<acronym>ARC</acronym>) caches the compressed version of the data in <acronym>RAM</acronym>, decompressing it each time it is needed. This allows the same amount of <acronym>RAM</acronym> to store more data and metadata, increasing the cache hit ratio.
即使数据更新频繁,也常常会因为启用压缩功能而获得性能提升。其中最大的优势来自于压缩的ARC功能。<acronym>ZFS</acronym>的自适应替换缓存(<acronym>ARC</acronym>)将数据的压缩版本缓存在<acronym>RAM</acronym>中,在每次需要时对其进行解压。这使得相同数量的<acronym>RAM</acronym>可以存储更多的数据和元数据,提高了缓存命中率。

<acronym>Zstd</acronym> provides a large selection of compression levels, providing fine-grained control over performance versus compression ratio. One of the main advantages of <acronym>Zstd</acronym> is that the decompression speed is independent of the compression level. For data that is written once but read many times, <acronym>Zstd</acronym> allows the use of the highest compression levels without a read performance penalty.
<acronym>Zstd</acronym>提供了大量的压缩级别选择,可对性能与压缩比进行精细控制。<acronym>Zstd</acronym>的主要优势之一是解压速度与压缩级别无关。对于写入一次但读取多次的数据,<acronym>Zstd</acronym>使用最高的压缩级别时不会影响读取性能。

In <acronym>OpenZFS</acronym> 2.0, a new compression algorithm was added. Zstandard (<acronym>Zstd</acronym>) offers higher compression ratios than the default <acronym>LZ4</acronym> while offering much greater speeds than the alternative, <acronym>gzip</acronym>. <acronym>OpenZFS</acronym> 2.0 is available starting with FreeBSD 12.1-RELEASE via <package>sysutils/openzfs</package> and has been the default in FreeBSD 13-CURRENT since September 2020, and will by in FreeBSD 13.0-RELEASE.
在<acronym>OpenZFS</acronym>2.0中,增加了一种新的压缩算法。Zstandard (<acronym>Zstd</acronym>)比默认的<acronym>LZ4</acronym>压缩率更高,同时比<acronym>gzip</acronym>速度更快。<acronym>OpenZFS</acronym> 2.0 从 FreeBSD 12.1-RELEASE 开始通过 <package>sysutils/openzfs</package> 提供, 并从 2020 年 9 月起成为 FreeBSD 13-CURRENT 的默认版本, 并将在 FreeBSD 13.0-RELEASE 中使用。
