Hi, Try [EMAIL PROTECTED] instead.
Bye. Geof. -----Message d'origine----- De : mos [mailto:[EMAIL PROTECTED] Envoyé : vendredi 25 mai 2007 06:41 À : mysql@lists.mysql.com Objet : MySQL 5.0 creates 100,000 Window handles I noticed if my program executes a lot of Select statements, Windows XP will slow down when the program completes. I did some investigating and mysqld-nt.exe has close to 100,000 handles created when my program ends (shown in Task Manager and SysInternals Process Explorer). As each Select statement is executed, 2 handles are created. These handles will stay allocated until the MySQL server is stopped (stopping my program won't free up the handles). Windows of course runs slow with this many handles allocated. 1) What is MySQL using the handles for? 2) Is there any way to stop MySQL from consuming so many Windows resources? 3) Is it like this on Linux? 4) How does a MySQL server handle millions of queries on a large table? Will it hit an upper limit of Handles that it can allocate? Note: it does not appear to allocate more handles if the query is found in the query cache.
