What constitutes a large table?

[Kenneth Vogt]

I have a table that has regular inserts made to it, no updates ever, and infrequent deletions. That is, it may have 50,000 inserts a day for a week before anything is deleted. This table has held up to 1,500,000 rows. From what I read about benchmarks, mysql should be able to handle a table 100 times this size. And yet the indexes seem to get corrupted easily. Is there some way to avoid this corruption problem? Is it a performancing tweaking issues? What oh what am I doing wrong?
