Hi all, I have written a block device driver. Driver includes the implementation of write back cache policy. Purpose of the driver is not an issue. The problem I am facing is the considerable difference of performance when I run same driver on 32 and 64 BIT OS. I am testing the driver on 64 Bit Machine and run the same driver on both (32 and 64 Bit) OS. On 32 Bit, IO rate is almost double then on 64 Bit OS. ( i wish it could have been opposite :( ) Is there anything to do with 64-Bit kernel compilation issue. What areas I have to look for?? I have used a few threads. Is there anything to change related to thread priority or attributes?? regards Nauman - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
