[Alexander P. (JIRA) <tr...@fi...>]

Performance regression - too many semop() system calls
------------------------------------------------------

                 Key: CORE-2050
                 URL: http://tracker.firebirdsql.org/browse/CORE-2050
             Project: Firebird Core
          Issue Type: Bug
          Components: Engine
    Affects Versions: 2.1.1, 2.5 Alpha 1, 2.0.4
         Environment: posix
            Reporter: Alexander Peshkov


Class BtrPageGCLock always explicitly releases locks taken to protect index pages from garbage collection instead of AST use. This leads to abnormally intensive flow of semop() system calls, causing performance problems when inserting records in a table with too many indices.
