![]() ![]() Many of the early restrictions and constraints have been removed, and several major features added. Mysql> show global status like 'com_select%' Ĭalculating innodb buffer pool hit ratio query cache hit ratio = ((Qcache_hits) / (Qcache_hits + Com_select)) * 100įirst, figure out your query cache hit ratio. With the release of the second version of the D-STAR Gateway program, the rules have changed significantly. #DSTAR DSYNC STATUS PAGE UPDATE#If most queries are SELECT and update query is rare, I think increasing query_cache_size is very helpful for you.Ĭould you post your query cache status as follows? mysql> show global status like 'Qc%' I think this value is too small in your case.

Calculating innodb buffer pool hit ratio mysql> SHOW GLOBAL STATUS LIKE '%innodb%' Both SSD and HDD are test.Īnyway you should increase innodb_buffer_pool_size. Benchmark your particular configuration to decide which setting to use.īut in my experience, there was no significant difference between O_DIRECT and O_DSYNC. Finally, restart Sendmail with a service sendmail restart. Save the file, then run the command newaliases to update the database. MySQL Manaual saysĭepending on hardware configuration, setting innodb_flush_method to O_DIRECT can either have either a positive or negative effect on performance. Open /etc/aliases in a text editor, go way down to the bottom of the file, and paste in the following: Who should we send D-STAR notifications to. Generally speaking, O_DIRECT is little bit fast because InnoDB Buffer Pool caches Data+Index, So with O_DIRECT disabled File System Page Cache is faster. Here's a script that installs an updated DSync script and configuration files that will report Version 3. I strongly recommand that you should increase it's value. Recommandation is set to 50~75% of main memory. Major problem is innodb_buffer_pool_size is too small. ![]()
