Hi all,

I have a weird problem. I have a myisam table with about 30.000 rows.
When i set read_buffer_size=400M it works but really slow. When i set it read_buffer_size=4G it is really fast but count() function gives null.
Also select * from table gives null but if i limit it such as "select * from table limit 0,100" it is ok.

What can i do?
