Hi,<br><br>I tried getting our server setup for 400-500 simultaneous calls, calls were going through properly but at around 200-250 calls, mysql (connect ...) statement was taking at least 5-10 sec to connect to the database. I optimized all possible parameters in my.cnf:<br>
<br>max_connection=1000<br>wait_timeout=60<br>query_cache_type=1<br>query_cache_limit=4M<br>query_cache_size=512M<br>interactive_timeout=120<br>connect_timeout=80<br>table_cache=1024<br>thread_concurrency=8<br>long_query_time=10<br>
tmp_table_size=64M<br>join_buffer_size=1M<br>thread_cache_size=200<br>key_buffer=32M<br>table_cache=1024<br>sort_buffer_size=2M<br>read_buffer_size=2M<br>read_rnd_buffer_size=4M<br><br>And I am running on asterisk 1.4.22.1, Quadcore processor 2.4Ghz, 4GB RAM, mysql 5.0. Some times we get dead air even after 50-100 calls. Is there any other additional parameters or variables or resources (hardware) to be looked into to increase the speed of mysql connections?<br>
<br>Your advice is really appreciated.<br><br>Thanks<br>Sandesh.<br><br>
