Re: OS Benchmarking for 6.4 vs. 6.3.0
For 2), I don't think it's a good idea to work around the OS allocator and provide an own/older one. That as well may
have undesired side-effects. ;-)
Has the customer tried 6.3.2? AFAIK memory management has been completely rewritten in this kernel version. There also
was an option to delay memory initialization until first use, if I remember correctly, which should speed up application
startup time.
With 6.4, I believe the 'big page' support will help your customer. Especially during startup time, memory configuration
is constantly changing and thus, tons of TLB reloads surely happen. There should be less with 6.4, resulting in better
speed.
But all these are just my personal guesses, I'm sure QNX HQ will come up with some solid benchmarks.
