MediaWiki file download REALLY slow

I have installed MediaWiki on Ubuntu 9.10 and everything seems to be working fine, except that when I download a file it is really slow.  It is downloading at <50 bytes / sec, so that it'll take 15+ mins to download a 45 KB file.

The server is on a local gigabit network and the system is responding well to any other call.  Web browsing is fine, I can perform admin backup speedily, FTP, SSH, etc.

The server is a VM on the free version of VMware ESXi 4.0.0

I am at a loss as to what it could be.  On the odd occasion it downloads fine (small files are almost instantaneous) Any ideas?


Version Info:
MediaWiki 1.15.0
PHP 5.2.10-2ubuntu6.4 (apache2handler)
MySQL 5.1.37-1ubuntu5.1

No. Will do.  Why would that affect things?

Doesn't look like there are VM Tools for 9.10.

A reboot has helped, but there is still a few files that exhibit this slowness.

Hi!

Is it only MediaWiki downloads on the Ubuntu-server (hosted in VMware) that are slow? Does downloads from Apache in the same virtual Ubuntu-server transfer quickly? Or did you refer to transfers between the VM-server and the Gigabit network when you said web browsing and FTP is ok?

Regards, Tobias

Everything else seems ok.  Even browsing the wiki.  The VM only is for MediaWiki, however, there are some supporting services, such as FTP, SSH, and the required stuff (PHP. Apache, MySQL).

Did you reboot the VM-host (the Ubuntu-server) or did you reboot the VM-server?

Is it only some files that are slow to download? Is it the same files all the time that are slow to download?

Regards, Tobias

It is happening again....  Downloading uploaded files that are stored in the web root are VERY slow.  I have moved other files into the www directory and they download fine.  I will see if they download fine the next time the system slows down.


A reboot of the VM guest (Ubuntu) has made it normal again.
