OMERO.web "production" environment is very slow

[uestra]

Hello,

i have problems with a very slow production installation. I used this howto:
http://www.openmicroscopy.org.uk/site/s ... nstall_web

now it needs about 4-5 minutes to see the login. this the same for every action after that.
there is no information in the logs:

Code: Select all

-rw-r--r-- 1 www-data www-data 0 2010-03-01 13:01 OMEROweb.log
-rw-r--r-- 1 www-data www-data 0 2010-03-01 12:57 OMEROweb.log.2010-03-01


the database permission:

Code: Select all

-rw-rw-rw- 1 www-data www-data 35840 2010-03-01 13:18 db.sqlite3


Code: Select all

the apache access.log looks good:
[code]
172.25.2.42 - - [01/Mar/2010:12:10:21 +0000] "GET /webclient/login/?url=/webclient/logout/ HTTP/1.1" 200 996 "http://172.25.103.93/webclient/" "Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.2) Gecko/20100115 Firefox/3.6"


i have checked the troubleshooting site, but now i need help.

best regards
mike

It is an Ubuntu 9.10 VM in a VMware ESX Server and Omero-Beta-4.1.1.

We haven't noticed that but we're also not running Ubuntu 9.10 here. I'll see if I can whip up a virtual machine and check it out. There's a ticket for this up on the Trac now which you have been CC'd on:

http://trac.openmicroscopy.org.uk/omero/ticket/1838

Let me know if you'd like your e-mail address taken off the CC of the ticket.

I have installed a virtual Kernel package:
linux-virtual
new vmware tools
and:
disable tcp windowscaling
rewrite omero websettings

Restart Omero and the Apache. After that, the installation is fast enough.
So this was a configuration Problem.

Thanks
Mike
