Out of curiosity, how many queries/sec are you able to push from each
slave? If I may ask.. :)

Anyway, did you enable the slow query logging? That still might give
you an idea if something is running slow. But I also forgot to ask
earlier, what is running slow, the inserts or the selects during the
Inserts are of the form (updates are analogous):
insert into dns_records (zone, host, data, ... )
values ('domain.com', 'www', '1.2.3.4', ... );
Queries are of the form:
select ttl, type, mx_priority, case
when lower(type)='txt' then
concat('\', data, '\')
Hi guys,
We have a MySQL database that we replicate to about a dozen clients
and we hope to be increasing that number to about 15-20. The database
has two tables. One is negligably small and changes maybe once a
month. The second is about 1.3 million rows and grows at the rate of
about
I could be wrong BUT...
1) Does increasing the number of replication slaves increase query
latency on the master? We're considering tiering the replication if
it might help - replicate the master to two slaves, each of which
replicates to ten clients.
The slaves should only be pulling from
Also, what type of database are you using? INNODB? MyISAM? If you
are
running MyISAM then things can get slow on updates.
Sorry, I missed where you said you were using MyISAM.

The table is MyISAM. I searched on google a bit for info on slow
updates with MyISAM and didn't really hit it on the nose. Can I ask
you to elaborate?
In /etc/my.cnf try adding:
long_query_time = 1
log-slow-queries=/var/lib/mysql/mysql-slow.log
Restart and then watch the file. If a

Hi,
I have gone through the MySQL documentation and FAQs. But
still I have a few questions -
1. Is there a performance comparison between MySQL Pro and MaxDB?
Is MaxDB much better than MySQL?
2. Does MaxDB also has a C/C++ interface?
3. Is replication supported by
