Since page size(PAGE_SIZE) on 32bit m/c is 4k, so this much max read/write can be done in one go. Rather on 64bit m/c it can be more than 4k as the page size is more than 4k. ----- Original Message ----- From: "Sandeep Tyagi" <sandeepktyagi@xxxxxxxxx> To: <kernelnewbies@xxxxxxxxxxxx> Sent: Friday, April 01, 2005 4:40 AM Subject: How to increase IO size of buffer cache > Hi - > We are writing a file system in which we need to read/write blocks of > size greater than or equal to 4K in one go.
