Hi, I run my production stuff on Ubuntu Server and have been using the pre-emptive kernel which runs at 1000hz, this was because previous build of FreeSWITCH seemed to need to run at this frequency. In testing the latest Ubuntu LTS release, it seems they're not producing recent kernels for anything other than their generic Kernel, which runs at 250hz I believe. Is it still a requirement / recommendation that FreeSWITCH runs on 1000hz boxes? I know the preferred distro is Centos, but would appreciate some guidance on what may occur if I were to move to 250hz kernels on production boxes, obviously this would still be a "softly softly" move. Thanks, Neil. -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Kernel-frequency-tp7528206.htm... Sent from the freeswitch-users mailing list archive at Nabble.com.
