;# A word on tuning your Odoo Server
;#-----------------------------------------------------------------------------
;#
;# A lot of time has gone in to testing this TKL appliance, and one thing we
;# learned while testing was tuning. For all the why we chose these numbers you
;# can take a look at he issues on GitHub (links at the botton of this article)
;#
;# Most of this text here was taken from the Memory Matrix Discussion
;# https://github.com/DocCyblade/tkl-odoo/issues/49#issuecomment-148881166
;#
;# It is important to note that you can run Odoo in threaded mode by setting
;# the workers option to 0 however there are some modules that won't work
;# and you loose fine grain control of resource management.
;#
;#-----------------------------------------------------------------------------
;#
;# the --workers is how many new process will be started to perform work or
;# (answer requests) The workers have limits upon them set by the limit_xxxxx
;# options here in the config file.
;#
;# The "limit_memory_soft" limit is the amount of ram that when a process
;# goes over this limit after it is done with the request it is terminated
;# and the memory it was using is freed. This amount goes for each process
;#
;# The hard limit is the amount of ram that if the process goes over it,
;# it WILL terminate right then. (I don't think this is really correct
;# because of the PDF issue we had and set this to 1.3 GB and never
;# saw a process take this much. but if its below 1.3GB PDF are not created)
;#
;# The one we need to pay attention to is the limit_memory_soft.
;# As these workers will stay alive and hold on to memory until that limit
;# is reached. So if you have 5 workers and the soft limit is 256MB you could
;# end up with 5 workers each taking 256MB that's 1.25GB of RAM that could
;# be taken up. If you only had 1GB of ram you may need to dial back your
;# workers or your soft limit.
;#
;# It's a balancing act of sorts, I am also not sure if keeping the
;# workers at say 350 or 400 if there is some caching effect. Not sure
;# why it's holding on to the memory.
;#
;#-----------------------------------------------------------------------------
;#
;# Hardware Matrix for recommended values:
;#   (Note these are for REAL hardware, Virtual Hardware has it's own
;#     issues that can arise with too many guest on a host with too many
;#     CPU cores etc, so remember that when looking at the chart below)
;#   (One other note that when I tested these, I did use VMware but
;#     no other VMs where competing for resources)
;#   (One last note, really. These numbers are to show the relationship
;#     between the config settings and hardware. We also assume you are running
;#     the database server on the same server. I know at some point in the
;#     higher numbers that this would not be the case. These are not numbers
;#     set in stone nor numbers gotten from Odoo. These are numbers I have
;#     come up with from the testing I have done. Real world examples if you
;#     have them would be great and these numbers can and should be updated!

;# Max Mem            | Maximum amount that can be used by all workers

;#
;# Note: Max Memory if notice is less than total memory this is on purpose. As
;#       workers process requests they can grow beyond the Mem Per limit so a
;#       server under heavy load could go past this amount. This is why there
;#       is "head room" built in.

;
; You should use 2 worker threads + 1 cron thread per available CPU,
; and 1 CPU per 10 concurent users. Make sure you tune the memory limits and cpu
; limits in your configuration file.

;http://odoo.com.au/recommended-server-specifications-for-odoo/
;Requirements for running Odoo 9 Community and Enterprise are the same.
;
;For a 5 user site = 2 CPU server and 2 GB Ram
;
;For 20 user site = 4 CPU server and 8 GB Ram
;
;For 100+ user site = recommend splitting app and database servers, 2 x 8 CPU servers with 32 GB Ram

If I do get Odoo started, I am also unable to login from erp.server.com as when I load the url it automatically transports me to https://erp.server.com/web/database/manager#action=database_manager

Thanks for your support.
