And this section in http://www.percona.com/docs/wiki/patches:innodb_io_patches 
  is unclear on the details...

"innodb_adaptive_checkpoint (default 0) - control the added feature  
adaptive checkpointing(*). 0:disable adaptive checkpointing, 1:enable  
adaptive checkpointing. attention: innodb_adaptive_checkpoint needs  
larger transaction files, in some cases. (innodb_adaptive_checkpoint  
makes the limit of modified age lower)"

When does this option require larger ib_logfiles, and how large (and  
how many) should they be then?

Thanks
Arjen.

They seem to have a lot of duplication, and I'm not sure which one is the
"real" patch page.
