Hi Our warehouse is separate from our office, Openerp connecting via the internet. LAN side it takes less than a second to load a page Internet side its a slow and painful 15 to 30 seconds to load a page!
We have 10MB download, 5MB upload microwave broadband at Server side. We have 2MB download 0.25MB upload at client
We use dynamic IP. - have tested with and without this, but no change?
Edit
Have been doing some testing and a quick review of the "log in page" using this gave this.
Not that I understand the results! But 17/100 isnt good! I see one immediate area for improvement
Enable Compression - advise is to "Compressing resources with gzip or deflate can reduce the number of bytes sent over the network"
Edit 2 We have an 1/100 improvement :) - installed nginx - now scoring 18/100 - 82 more to go - still no compression!
Edit 3 We have had a small improvement :) - by changing the router - now scoring 34/100 - 66 more to go - still no compression!
Edit 4 We have had yet another small improvement :) - by giving the server another 2GB of memory - now scoring 36/100 - 64 more to go - still no compression!
Edit 5 Using Laura's link to Olivier below and "debugging tools" we have deduced that's its the first 2Mb of Java that's the slowing factor! Hence why I get a naff score when I test the log in page! (ok this is leading towards naff b'band, but - also noticed a couple of open wireless networks that we have tried (eg at shows) have what appear to be DNS issues somehow we can surf, but not use Openerp (cannot even ping)) .Once past the login page their is very minimal traffic!) I would still love to be able to enable compression on the 2MB of java! Any ideas?
do you access openerp on port 8069? did you install a proxy (nginx/apache) in front of it?
Yes I have access to 8069 - didnt install a proxy! I know I have mod_deflate already installed which works (tested http://www.whatsmyip.org/http-compression-test/) on port 80 but not working on 8069! Should I have installed a Proxy? - Now install nginx see edit 2 above
Bandwidth is not everything regarding network performance. What is the latency from the remote site to the server? are there any lost packets? Try this command while using OpenERP:
ping -n 200 YourOpenERPServer
and post the result (last line)vote for this. i think my installation is slow over internet too. i try other erp software on the same server its load faster. why openerp is slow there must be some problem that i do not know. over lan its ok.
