MySQL Partitioning 5.1 - Part 5 Slowdown Problem Solved!

Finally figured out what was causing the lack of performance on the
partitions with the query. The use of FORCE INDEX was causing the slowdown
with the partitioned table. Once I removed the clause, the query ran in 1
minute 19 seconds, which is more in line with expectations. Sorry for any
inconvenience!

Partha,

I am evaluating a switch from MySQL5.0 to 5.1,( and I found some interesting inputs on your blog. ) and it would be really helpful to me, if you could provide useful inputs in this regard, or point me to the appropriate resource(s).

To briefly explain my situation, I work on building large scale distributed systems that are intended to scale to a few hundred transactions per second. We are seeing progressive degradation of response times with data size, and want to switch to MySQL5.1 for the benefits of Partitioning.

Runes of Magic is a Massively Multiplayer Online Role playing Game without monthly costs all kinds of Rom Gold and free to download. The premise is that you have played this game and understand the necessary Runes of Magic Gold in the Runes of Magic game. Perhaps the first monster I saw taken down in the demo can gain those varieties of Runes of Magic money. Characters choose one class; the important one is that we have to buy Rom Gold first. You can switch freely between the two classes, but you can only use primary abilities from your primary class, along with cheap Runes of Magic Gold, secondary abilities from your secondary class.
It is easy to control and pick up more all kinds of latale online gold and weapons or equipment which were dropped by those monsters. You will experience a wide range of attack and strikingly gorgeous combat effects with your own latale gold. You can also freely customize your character by equipping cool armors and weapons which those you must first have need to buy latale online gold and then you can have them. There is no doubt La Tale and its very cheap latale gold will attract female gamer and as well as young gamer eyeballs. You see my problem is that I do not what class is good or fun to play without any more necessary latale money.
