Note that this feature does not apply to Rack applications. :( Cheers, Ohad On Tue, Jan 13, 2009 at 9:39 AM, Ohad Levy <ohadl...@gmail.com> wrote: > Hi, > > I think that there are two points here, > > One is passenger with standard ruby, and the other with REE. > > As far as Passenger goes, I would recommend it to people who start fresh > (e.g. migrating from webrick). > > for REE - memory usage, I thought that passenger REE(GC) optimizations are > not relevant to rack applications, however, I spend the last 30 minutes > looking for that article I had in my mind, so maybe I'm wrong about it. > > Currently, when I have a mongrel process which abuse memory, monit restart > it, which causes some clients to think the server has gone away (not sure > why apache doesn't move it to another process) - but that happens so rarely, > that its not a huge motivation to migrate. > > All in all, passenger simplifies a lot when it comes to managing > puppetmaster processes, and its also dynamic (e.g. it wont load a lot of > processes if there is no need) - so maybe it would save memory usage anyway. > > How do people benchmark? anyone has a good way to simulate load? > > Ohad > > > On Tue, Jan 13, 2009 at 8:43 AM, Thom May <t...@joost.com> wrote: > >> >> On Mon, Jan 12, 2009 at 16:31, Luke Kanies <l...@madstop.com> wrote: >> > >> > Hi all, >> > >> > I know people have used Puppet with passenger[1], but has anyone tried >> > it with Ruby Enterprise Edition[2]? >> > >> > The producers of REE claim that the two in combination can cut Rails >> > memory usage by 33%, and I'm quite curious if it has a similar impact >> > on puppetmasterd.
