orbiter 035ebfbf3b - performance hacks (should affect the crawl balancer and reduce CPU load during crawl stack re-fill)
13 years ago
orbiter dad5b586a4 added a concurrent warmin-up of Table data structures. that should speed-up the start-up process but may also cause stronger CPU load at that time.

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.

low012 3b40b98256 *) set SVN properties
14 years ago
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 362b7a929b added extensive memory protection logic to avoid out of memory errors that may be caused by the RowCollection memory allocation function
15 years ago
orbiter 4a5100789f replaced _all_ size() == 0 with isEmpty() and all size() > 0 with !isEmpty(). The isEmpty() method is much faster in some cases, especially when used to access badly balanced hashtables where an size() operation becomes a large iteration.
