I think you might be interested in my database size. The whole database
is currently on 15 servers and I think it's about 60.000 of tables
containing about 5.000.000.000 of rows. My mostly loaded server
currently holds about 10.000 of tables with 1.000.000.000 of rows in it.
Hugest tables have about 50.000.000 of rows, and this value will raise
as soon as I'll move to 2.4 kernel with large files. Currently I have to
delete much of logs for large sites to hold table sizes in 2Gb.
