<font face="trebuchet ms,sans-serif">I tried it on asterisk version 1.8 as well as other minor releases of 1.6. Its the same. Not a silly question, since silly products usually have instantaneous errors vanished by a silly action :)<br>
I tried </font><font face="trebuchet ms,sans-serif"> changing </font><font face="trebuchet ms,sans-serif">different parameters in cdr.conf and reloading multiple times...<br>Yes, I am just using the default CDR backend and I check CDR population via <AST_LOG_DIR>/Master.csv<br>
By the way, even if I use the mysql backend, its the same result. the CPU load is negligible and call quality is fine but still CDR write speed is almost 1 entry /1.5 second. I highly doubt that would be the max write speed!<br>

<p>Asterisk can cache cdr records to avoid having to write continuosly in the cdr backend. Writing in bunch instead one at once improves performance. Check the cdr.conf file and disable the option "batch" if it hurts you.</p>
