increase bulk_insert_buffer_size and if possible split the bigger file into
small chunks. It will help you.

Hi All,
All,
I will be recording timezone information based on user input using the
time zone names from mysql.time_zone_name - names
like 'America/Los_Angeles'.
When recording this information, do I store the full name or just
the 'time_zone_id' which is present in mysql.time_zone_name ?

Hi list,
Have a bit of a mystery here that I hope somebody can help with.
I've just got a new server that I'm using as a dedicated MySQL server.
In terms of hardware it's pretty much identical, if not slightly
superior to an existing server already in production use.
It's having a real struggle
Please check if the my.cnf configurations to be the same.
What are your configuration parameters in terms of innodh flush log trx
commit , bin logging, sync binlog and innodb unsafe for binlog ?
If the systems have raid, check if the BBWC is enabled on the new host and
WB is enabled.

Hi Alex,
Configurations are identical, other than the differences I initially
mentioned. I've diffed both the configuration files and the output of
SHOW VARIABLES on both servers.
I've contacted my hosting provider to ask about the RAID settings.

check for iostat to see if the disk is heavly used.

also how often do you issue a commit. batching the inserts inside a
transaction might help.

Hi guys, thanks for pitching in.
The inserts are from replication; we're not using transactions on the
master (yet), and I don't think there's a way of telling MySQL to batch
incoming replication statements if they're not already in a transaction.
Disk usage: the older server (the one that's
replication based inserts are serial whereas most of the time the inserts on
masters are concurrent. this leads to the slaves falling behind. to tackle
this we have used the following strategies :
1. Use raid 0 on the slaves (master users raid 10) so as to speed up writes.
2. pre fetch and cache
Disk usage: the older server (the one that's running fine) is running
more transactions per second, but has lower blocks written and read per
second than the new server:
[JS] That, to me, suggests that the difference might be in the way the systems
themselves are configured. Unfortunately, I
Hi Guys,
Having delved a little more into the capabilities of iostat, I've
discovered that the drive bandwidth seems to be maxed out while MySQL is
running, which I'd peg as the primary candidate for the problem.
Looks like I'll be having more words with my hosting company about
this...
Thanks

[JS] That suggests even more strongly that there is a difference in the kernel

Why not switch to Sphinx full text search for MySQL? It is faster and can
handle more data than MySQL's built in fulltext search.

That's pretty much what I've been doing to get that the drive is running
at 100% bandwidth.
What I'd like is something that just gives the bandwidth of the device
in terms of Mb/s: you can probably work it out using that iostat
command, seeing how much it wrote and what percentage of the
Hi, I am sorry for being so vague. The values are not as simple as jane20,
jane10, or jane2. There are names like, jane-2, alex 3, alex4, and just

as I can tell. I'll have to think about zero-fill, but I doubt that
If you are using MySQL 5.0 or later, use the INFORMATION_SCHEMA database.
It has an in-memory table of table names called (as you would expect) 'tables'.
SELECT table_rows,table_name FROM information_schema.tables
WHERE table_schema = 'whatever database you choose';

where tNm1, tNm2 are table names in the database.
