[PATCHv2 1/3] lib: vsprintf: optimised put_dec_trunc() and put_dec_full()
The put_dec_trunc() and put_dec_full() functions were based on a code optimised for processors with 8-bit ALU but since we don't need to limit ourselves to such small ALUs, the code was optimised and used capacities of an 16-bit ALU anyway. This patch goes further and uses the full capacity of a 32-bit ALU and i... 8 Aug 2010 16:43

[PATCHv2 2/3] lib: vsprintf: optimised put_dec() for 32-bit machines
Existing put_dec() function uses a do_div() function for dividing the 64-bit argument. On 32-bit machines this may be a costly operation. This patch, replaces the put_dec() function on 32-bit processors to one that performs no 64-bit divisions. Signed-off-by: Michal Nazarewicz <mina86(a)mina86.com> --- lib/vs... 8 Aug 2010 16:43

FCNTL Performance problem
Hi, We use CISAM files a lot in our application, which uses the FCNTL system call for record locking. I've noticed a possible problem in though with FCNTL, after a lot of work using the systemtap tracing program. The problem is, when you have lots of F_RDLCK locks being created and released, then it slows ... 11 Aug 2010 13:39
