There is a limit, but that is really limited to the hardware you are running it on. You need to figure out what part of your system is bottlenecking (disk I/O, RAM, CPU, or network I/O). Perhaps you have to little RAM and/or your mysql configuration variables are not set optimally. Too little RAM means more disk I/O, which then kind of compounds itself.

I have notices some slow queries showing up in my slow query log lately. Two of these queries are relatively simple queries using the index of their respective tables. Both of these tables are very large and I suspect this to be the problem. This problem appears to have started within the last couple of months. These tables grow in data daily.

Table 1
--------
Rows: 17,794,256
Index Size: 511,596,544

Table 2
--------
Rows: 43,513,707
Index Size: 1,009,502,208

Is there anything that I can do? I have optimized the tables, but it did not appear to help. Is there a limit to MySQL efficiency and table size?
