Indeed. InnoDB is much slower overall compared to MyIsam. However, it has its use for some jobs (archive_logs, hot backups, etc.)

The figures I gave were sustained rates simulated with a 10000-SMS batch. Count was sufficient to reach sustainability and reproducibility, yet short enough to get results fast.

When i submitted fakesmpp, I also released similar data from a 64bit Solaris 10 server.

Brett,

The DLR engine uses SELECT COUNT(*) from the admin interface, which is painfully slow on InnoDB for moderately big tables.

While InnoDB would theoretically be the best option, MyIsam performs quite better in this case.

Hi Nikos


Thanks for the extra information. What was the motivation for using MyISAM? My reading lead me to believe that MyISAM was not that well suited for interleaved reads and writes due to table locking which is why I opted to use InnoDB. From what I assumed about how Kannel worked is that reading/writing to the DLR table would be interleaved. I may be quite badly mistaken and might perhaps need to switch to MyISAM as a few others have recommended.


In your opinion what should Kannel be able to handle sustained (assuming normal business hours)? And what should Kannel be able to burst to? I know some of these questions are a bit like how long is a piece of string but I really do value all and any of your feedback.

Try valgrind in linux.

Yeah I understand that. But when the there is no traffic. Kannel doesn't release the cached or buffered memory it used. Do you have any solution? What command to list down or trace the memory usage by Kannel? So maybe we can investigate which function or module in Kannel is eating the memory. Thanks

No memory problems. It is reasonable that kannel will use more memory in higher traffic, since all queues are in memory, as long as it drops to nominal levels once the traffic is gone.

Hi Nikos,
Do you experience memory problem? In my case Kannel is eating the memory on high load traffics. I always need to restart the box to get more memory. I even give 3 on /proc/sys/vm/drop_caches but still Kannel eat the memory :(

Hi Nikos

Out of curiosity can you go into more detail regarding what hardware you were running and your setup for MySql? Were you using Innodb or MyIsam. If you were using Innodb did you make any other configuration changes to MySql to accommodate Innodb.

From the user guide it is implied that the bottle neck for Kannel is the number of messages that the SMSC can accommodate per second. Is this still the case?

Hi,

I have run some benchmarking for a client using fakesmpp. Using the default service for MO's I got:

MO's: 1400 SMS/s
MT + DLRs (internal): 747 SMS/s
MT + DLRs (MySql): 434 SMS/s

Nikos

Hi,


I am interested to know about the kannel performance benchmarking, especially in terms of speed (msgs/sec), MO or MT. I assume that multiple smsboxes does not have any effect over kannel performance, since the front-end talking to SMSC is the main bearerbox. What is the max speed that could be attained by kannel and/or bearerbox?


Regards,


Hamza
