Hi Andrey, > > I see... Nevertheless, I am surprised that context switch is so expensive.
Especially on ARM9 Platform a context switch takes very long time. The reason is the cache implementation, that requires to flush instruction cache and data cache at each context switch. There is a patch for the linux kernel called Fast Context Switch Extension (FSCE), that speeds up the context switch a lot. If you have installed i-pipe you should find it within the kernel config. Have a look at it's restriction that are mentioned in the config's help.
