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?
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?
LAN side it takes less than a second to load a page
If OpenERP is performing well via the LAN, then you should concentrate exclusively on the network.
Three most common causes of slow network performance:
- Congestion (too much traffic from too many users)
- Data corruption (traffic being sent more than once because it is damaged during transmission)
- Collisions (traffic being sent more than once because it can't make it the first time)
How do other client/server applications perform on this same network? If they are slow, then OpenERP will be slow.
We have several clients accessing OpenERP from hosted virtual servers on Amazon and Rackspace infrastructure and it is no slower than LAN access.
