Topic: Very slow file transfert witth apache

[bagu]

Hello,

I use apache 2.4.9 vc11 x64 on Windows 7 pro 64bits.
Using windows transfert, i get 70-80Mb/s but, using apache, i only get 20ko/s max.

I have set :
AcceptFilter http none
AcceptFilter https none
EnableMMAP off
EnableSendfile off

On my httpd.conf but nothing change.

Can you help me to find how to correct this ?
Thanks

Hello,

may i ask for some more information about your system?

1. How do you test? (Locally or via internet ...)
2. Do you have a virus scan running and scanning the network transfer?
3. What kind of apache configuration do you use? Especially additional packages?
4. After changing the conf and adding the directives "AcceptFilter http none" ... did you restart?

Of course you can ask

1- Locally and trough internet. The problem happen when i try to download a file attached with a mail on roundcube. But when i use thunderbird (imap) no problem happen and when i transfer files with ftp or samba shares, there is no problem.
2-No, only windows 7 firewall, but i have open the port 80/tcp

Ok, thanks for explaining.

So your problem depends on roundcube to load mails via imap which have files attached. right?
And loading the same mails with thunderbird via imap do not cause such problems. right?

So there must be something very special with the roundcube mailer in combination with your mailserver or in combination with apache.

What about logs?

[bagu]

Apache error log, php error log and rouncube error log are empty.

In fact, as soon as the download come from apache, there is two problems :
1-It's slooooowwww
2-The size can be find by browsers

[jraute]

What do you mean with "the size can be find by browsers"?

[jraute]

Since i am not a roundcube-expert i hope you find good tips here:

http://trac.roundcube.net/wiki/Howto_Config/Performance

[bagu]

It's not only trough rouncube...

The size can't be find...
So we i launch a download, web browser don't show me the download size, nor the estimated download time...

[jraute]

Did you check the links?
Is your database an sql-server on the same machine?
How is the connect organized?
What protocols are used between the components?

[James Blond]

Since it is in rounde cude. It makes sence to test a file download directly from the file system to see if it is the apache settings or to search somewhere else.

[bagu]

-An other link, wich is not in roundcube give me the same slow download, even on LAN
-I have chech the links and make some change on roundcube.
-Mail server and database are on the same computer. And roundcube is set to connect on 127.0.0.1 for database AND imap server.

So, as i have said, the problem is not only on roundcube. Roundcube pages are show correctly, messages are display quickly.

But, as soon as i try to download something on my webserver (LAN or WAN, roundcube or not) i only get a really slow download.

And if i try to make and ftp transfert, i get more than 10MB/s on lan and 120KB/s on WAN.

The slow download is only trough apache.

[James Blond]

Did you try EnableSendfile on yet?

[bagu]

No change with enablesendfile on or off

[jraute]

Ok, than try to configure a directory in apache, put a file in it and download via simple http.

If the download speed is still slow, try to disable modules (for example cloudflare, etc.), you don't need for the core apache functionalities and then test again.

And check for your cache configuration!

[bagu]

Here is my cache configuration :

[jraute]

I don't want to sound picky or smart-alecky but the mod_deflate modul is a compression thing. Maybe you don't use a cache directive, if not, no problem, but if and when, you should check your configuration for that as well.

Try to test with less moduls enabled - just the core components.

[bagu]

Ho, sorry, i read too fast and i was reading a post about size detection problem witch can come from deflate configuration.

Same problem with only core module (without cloudflare ,fcgid , expire and deflate - i don't know wich other module i can remove)

[jraute]

That's crazy.
Did you test with a simple file in a directory mapped to the apache?

And maybe you can copy that configuration to another computer and test again, but i don't have any further idea what to check.

Sorry bagu, maybe someone else can help you.

[bagu]

I've made a test with nginx, there is no problem : ARGH !


I will try to remove and reinstall apache from scratch.
There must be something i missed.

[bagu]

A complete re-install solve the problem.

I don't know what happen.
Thanks for your help.
