Walt, Yup, we use Innodb with 3.23.46 on Linux 2.4.2. I can't tell you whether things are better than they were on 2.2 kernels but we're updating tables just about that quickly I'd say. Largest table we have is a log table which has 50 million rows in it so far. Thanks to Innodb row locking, we've significantly improved insert versus select query performance.
I've heard (I think I read this in a magazine) that prior to 2.4.4 kernel, there are some virtual memory issues with Mysql, so I'd be interesetd to know what kernel version you have... memory management changed a lot between 2.2 and 2.4, so that would probably account for the changes you're seeing.
