50 sounds okay and sufficient.

But I do not get that much. I get about 50 of my transactions (2updates
+ 1insert + some selects) per minute!

I do not select the big table before inserting And yes, I do use
indices. But for one key there are only two different values in the big
table.

Also, please take note that I'm still using 6.2.1 for this test. I will
switch to 6.3. as soon as the ODBC driver is working again.
