Re: "Incorrect key file for table XXXX"

Shane,

A much appreciated side effect of the removal of the key_cache_block_size appears to be vastly more efficient CPU utilization. Previously, I would see roughly 75-90% CPU, but a quarter of it was system time. I never could get rid of it and had no idea where it was coming from. My KDE Sysguard CPU meter would rarely max out at 100% and there was always a significant amount of red system time.

Now, I have a sharp spike from 0 to 100% and a completely saturated blue box indicating 100% user time for the life of my longer queries.

It looks like I have roughly 25% more user time on hard queries. I wonder whether the system time was caused by mallocing and freeing memory.

Any other useful memory tricks?

Thanks 1E6,

BrianP
