however the download starts at 1 mbps but then drops down to 100kbps within seconds . Same is the case with skype calls . 1) what happens if you do video calls within your network? this should help you figure out if it an issue with ISP or internal issue. 2) sometimes there is bandwidth cap on the incoming data - imposed by certain ISPs - check if there any such with your ISP. 3) Does it happen only for video calls? what happens if you use wget ? ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

Based on my experience, observations are a.query analyser decides based on statistics of the data distribution. b.An IN+subquery means in-determinate number as opposed to WHERE. So it may be prudent to do a table scan than index lookup. That may explain why it uses ALL. c.Join on two large tables even on indexed field is not efficient. If such queries can be brought to IN+subquery I feel they will perform better. If chal table is large and c_users small then query 1 should be efficient. If both are large there may not be any difference. Raman.P blog:http://ramanchennai.wordpress.com/ Hi Raman, Thanks for explaining.

Optimize your SQL queries and tables. SELECT * FROM foo is never good
practice as it may force a full table scan and cause heavy disk IO. The slow
query log can help you identify the hot spots. Google mysql slow queries.
If you have large tables this is a really painful problem. I used to run
Request Tracker with a +25GB MySQL 4.x backend. Complex RT searches
could send MySQL spinning forever. Over time we learnt to tune our tables
and sanitize user queries. Many times the only way out was to simply restart
MySQL.
Btw, don't forget to check the MySQL bug tracker for any solutions/patches.
Thanks Raja,
