Hello list,
I have a table whose 'default charset=utf8'.
I insert a record into it with non-utf8 charset,like GBK.Then I select
this record,it print GBK characters correctly.
Then I insert a utf8 record into it,and read this record in scripts and
decode it with utf8_decode,the result is also

Hi Jim -
I'm using MySQL on Fedora 6 as well, with no performance problems. Did not
need to do anything to speed it up on Fedora.
It's difficult to answer the question why one is faster than the other, as

I don't think this is a bug. I think what's happening is that your
timestamp column can't hold that date, it's max value is somewhere in 2038.
So I guess either change your timestamp column to a datetime column, or
prevent users from putting invalid data in.

Your settings doesn't seem optimized much.
So here first question, do you use 32bits or 64 bits platform? If you
have 64 bits platform with 64 bits mysql and os you can boost most the
settings to use almost the 8G of ram you have on the server. If you are
using 32bits you will have to do some
