-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I want to say: A system with low consumpted memory will starts processes more quickly against system with low free memory and overloaded cheduler and more sleep processes in most cases. So, IMHO better solution is possibility to shutdown idle children after configured timeout and starts them up when required. Also, OS cache also still exists..... and can hold rewriter ELF near CPU.... did you remember? ;) 13.02.15 0:49, Amos Jeffries пишет: > On 13/02/2015 7:01 a.m., Yuri Voinov wrote: >> Hi gents, > >> subj. > >> And, of course - question.
