problem with query performance


hi,

 

i have biztalk solution receives xml messages emails translated them different format , adds sql 2005 table using sql server adapter in bts2006. bts2006 , sql works on different servers connected 1mb vpn.

sql server adapter uses ms dtc add translated data sql2005. during normal situation when adds 20-30 messages per minute ok.

but when e.g. bts stopped night , has add many messages, adds 10-15 per second. last 1-2h.

in same time impossible query database messages. takes long time, although sql server busy (procesor utilisation 5-10%). query uses many records because makes grouping, min, max, etc, operations. simple queries selecting few record id between 2 values works normally.

what's going on? ma there many locks? how check , improve it?

 

thanks,

przemo
