您通常可以在执行大容量索引时获得良好的查询性能，而无需求助于蓝/绿色设置。
以下是实现这一目标的一些要点：

如果您要插入大量文件，请尽可能使用https://github.com/lucidworks/spark-solr。它有相当容易使用的强大大量汇入机制。如果没有必要，请勿将您自己的大量汇入写入Solr程式码。
如果你必须使用solrj，请确保你是批量提交的。请参阅add(Collection<SolrInputDocument)方法。如果你用insert http请求淹没了solr，它会大大降低查询速度。
不要太频繁地提交。提交是昂贵的！
使用auto-warming。这是一个solr特性，它会在每次创建新的搜索器时（在提交之后）预热文件系统缓存。这对于确保在提交之后通过保持所有搜索都在有效缓存中来获得快速查询是至关重要的。
如果你有很多碎片（比如超过20个），可以考虑使用“交错提交”的方法，一次提交一个碎片。这里是一个Python例子，有16个solr服务器，总共有64个碎片。通过一次只提交一个碎片，可以避免同时提交整个集合，从而减少提交的影响。

确保你的过滤器缓存足够大。这样可以防止过滤占用CPU和磁盘IO，这样你在索引时会注意到很小的影响。
请考虑定期执行Solr优化。通过执行Solr优化，可以将更多的索引放入内存，从而减少磁盘IO。通过减少磁盘IO，新文档不太可能需要命中磁盘，从而提高磁盘性能。
如果Solr运行在共享硬件上，请确保运行的其他应用程序不会占用CPU和磁盘资源。例如，如果您正在使用Apache Tika解析文档，请确保Tika运行在另一台主机上。Solr最好保持独立。
请确保VM上有足够的内存用于文件系统缓存。例如，如果您有一台32 G RAM计算机，您应该考虑不要让您的最大堆大小太大。例如，如果您有-Xmx 28 G，它没有为操作系统的文件系统缓存留下足够的内存。请使用经验分析来确定您实际需要多少堆。例如，-Xmx 12 G将为操作系统的文件系统缓存留下50%的内存。的内存分配给FS缓存。在查询期间可以使用的缓存越多，索引对您的影响就越小。

编制索引通常会使查询变慢。如果磁盘速度快，编制索引将使用100%的CPU，否则将使用100%的磁盘带宽。无论哪种情况，查询都将变慢。
主/从配置是标准的解决方案。从服务器专用于搜索查询。唯一的一次它们变慢是在复制之后，当新的搜索器和新的缓存被创建时。
主/从配置可能不会使索引速度更快，但它可以避免查询性能降低。已经有一些工作在使索引成为多线程，因此您可能希望一次测试多个索引任务。如果瓶颈是磁盘IO，这将没有帮助，只有当它使用了一个CPU的100%时。
Trie字段非常适合范围查询。我怀疑它们会对索引速度有很大影响。
最后，您可能需要调整拼写建议选项。拼写建议可能是一项很大的工作，您可以使用不同的、成本较低的选项来获得良好的结果。
