Network Tweaking - Database Query Across Internet
Hi
We run a script that queries a database via the internet and we need the fast possible connections to the database server.
I have centos server which sends the requests to the database across the internet . it sends upto 800 queries per milliseconds however this using the default settings on our server.
Are their any tweaks we can make to the network card / settings on centos 5.4 ?
I have increased MTU frames to 1500 but thats about it.
Any suggestion would be welcomed

radrelay
RADRELAY(8) FreeRADIUS Daemon RADRELAY(8) NAME
radrelay -- Deprecated command. DESCRIPTION
The functions of radrelay have been added to radiusd. One benefit is that one instance of radiusd can read multiple detail files, among others. The rlm_sql_log module does something similar, but for SQL queries. See it's man page for details. REPLICATION FOR BACKUPS
Many sites run multiple radius servers; at least one primary and one backup server. When the primary goes down, most NASes detect that and switch to the backup server. That will cause your accounting packets to go the the backup server - and some NASes don't even switch back to the primary server when it comes back up. The result is that accounting records are missed, and/or the administrator must jump through hoops in order to combine the different detail files from multiple servers. It also means that the session database ("radutmp", used for radwho and simultaneous use detection) gets out of sync. We solve this issue by "relaying" packets from one server to another, so they both have the same set of accounting data. See raddb/sites-available/buffered-sql for more information. BUFFERING FOR HIGH-LOAD SERVERS If the RADIUS server suddenly receives a many accounting packets, there may be insufficient CPU power to process them all in a timely man- ner. This problem is especially noticable when the accounting packets are going to a back-end database. Similarly, you may have one database that tracks "live" sessions, and another that tracks historical accounting data. In that case, accessing the first database is fast, as it is small. Accessing the second database many be slower, as it may contain multiple gigabytes of data. In addition, writing to the first database in a timely manner is important, while data may be written to the second database with a few minutes delay, without any harm being done. See raddb/sites-available/copy-to-home-server for more information. SEE ALSO
