This is the size of the URL write buffer. Its purpose is to buffer incoming URLs
in case of search result transmission and during DHT transfer.

< td > #[wordCacheKSize]#< br / > (#[wordCacheKSizeKBytes]# KB)< / td >
< td >
This is the current size of the word caches.
The indexing cache speeds up the indexing process, the DHT cache holds indexes temporary for approval.
The maximum of this caches can be set below.
< / td >

< td > Maximum URLs currently assigned< br / > to one cached word:< / td >
< td > #[maxURLinWCache]#< / td >
< td > #[maxURLinKCache]#< / td >
< td >
This is the maximum size of URLs assigned to a single word cache entry.
If this is a big number, it shows that the caching works efficiently.

< td > Maximum age of a word:< / td >

This is the maximum age of a word in an index in minutes.

< td > Minimum age of a word:< / td >

< / td >
< td >
This is is the number of word indexes that shall be held in the
ram cache during indexing. When YaCy is shut down, this cache must be
flushed to disc; this may last some minutes.

< p >
This is the time delta between accessing of the same domain during a crawl. The crawl balancer tries to avoid that domains are
accessed too often, but if the balancer fails (i.e. if there are only links left from the same domain), then these minimum
delta times are ensured.

This is the time that the crawler idles when the proxy is accessed, or a local or remote search is done.
The delay is extended by this time each time the proxy is accessed afterwards.
This shall improve performance of the affected process (proxy or search).
(current delta is #[crawlPauseProxyCurrent]#/#[crawlPauseLocalsearchCurrent]#/#[crawlPauseRemotesearchCurrent]#
seconds since last proxy/local-search/remote-search access.)
