Now you are using memory tables, right? If so, then why "IO is quite saturated already"?, memory tables don't use IO. Do you have other app consuming lots of IO?

Since the table is small (only 100k), assign the right amount of memory to innodb, innodb doesn't need a IO if change a block as several changes to a block could be combined into one IO.
