orbiter d13103a0a7 changed the way how the index cache is flushed: do not flush when a put was made because that could cause that many put calls synchronize for a long time when the dump or a merge is performed. Instead a watchdog thread is doing the dump and therefore puts cannot block any more which is good when a put happens during a search result preparation.

orbiter 1912d0cccc changed handling of RowSet element retrieval: until today all elements had been copied from the underlying byte[] arrays into a new Entry object that again had a copy of a portion of that byte[] in its own bye[]. There was an option to just refer to the underlying byte[] with a pointer but that was almost never used. This commit now changes an interface to the Row class where it is now necessary to tell if a copy is always required. Fortunately the copy is only needed in very rare cases. That means that this change should cause much less memory allocation; it is expected that this happens especially during search situations.

orbiter cb1f49d0f2 replaced all 'new String' with default encoding (missing) or UTF-8 encoding with a String generation method that uses a pre-defined Charset constant for UTF-8. This avoids a cache-lookup for the Charset object using String hashing of the String 'UTF-8'.

orbiter 22dbbcfa56 better (and corrected) recognition of intranet and internet-addresses. This corrects the isLocal property that is used by network definitions to restrict index ranges to local and global addresses. Address locations (intranet or internet) had been partly identified by the top level domain of the host address. Since intranet addresses can also be addressed using a host name that is in a country domain it is necessary to do a dns resolving for each check. The check is supported by a local dns cache so the intranet/internet check should not affect network traffic too much. To ensure that the cache works properly the cache class was upgraded to better concurrency data structures.
