 === Data Settings
 
 The settings in this area control the numbers of threads that are allocated _per node_ by Couchbase Server to the _reading_ and _writing_ of data, respectively.
-The maximum thread-allocation to each is _64_, the minimum _4_.
+The maximum thread-allocation to each is _128_, the minimum _4_.
 
 A high thread-allocation may improve performance on systems whose hardware-resources are commensurately supportive (for example, where the number of CPU cores is high).
 In particular, a high number of _writer_ threads on such systems may significantly optimize the performance of _durable writes_: see xref:learn:data/durability.adoc[Durability], for information.
