Squid Proxy data transfer via download and Upload is very slow.
 

Dear Team,

We have Squid 3 installed on Ubuntu 13 server.
We have 40 MB Internet Pipe coming on Firewall Device . Problem is that When user downloading or uploading data vi Proxy server there data Transfer is very slow.

Ok, and as you've been told MANY times now, unless you provide DETAILS, there's nothing we can help you with. You say NOTHING about what the 'firewall device' is, how fast IT is, what kinds of speeds you're seeing, what logs you've checked, iptables/NAT rules, etc. Have you, as the administrator, checked ANYTHING yet? Is this a new problem? Has anything changed recently? Tried restarting squid? Flushing the cache? Any rule changes?? ANY details at all????

See your MANY other threads about Squid...pay particular attention to the ones you've asked about delay pools, transparent proxy, and bandwidth throttling, and think about how any of those topics would relate to slowing down of data transfer.

Thanks Tb0ne,

This is ISP issue. Now its working fine.

We had escalated to ISP and ISP confirm issue with there end.

Now Downloading speed is proper now it is 40 MB. but uploading is only 5 MB maximum.Internet is coming on direct Proxy server.

And??? Is this a problem? Did you check with your ISP to see what your UPLOAD speed is? You don't get the same speed for uploads as you do for downloads...

OK but it should be half means 10 mb to 20 mb at least. We had connect it on direct windows 7 system and checked it go up to 25 to 30 MB upload speed.

Ganesh, still no squid.conf , guess you actually dont need any help?

But maybe you could try speedtest from squid box and see the upload form that box.

Use command line speedtest http://xmodulo.com/2014/01/check-int...ine-linux.html

Also, afaik delay pools wont affect UPLOAD speeds.

I will share you squid.conf file soon.

we had checked through speedtest website and we able to get download speed 35 to 40 MB bot upload is not going above 4 to 5 MB.

Details:-
Suid 3
Ubuntu 13.

PFA of sqid.conf

So you have 5 MB upload as you tested. I dont see the problem then.

Also I just lost 5 minutes of life checking commented squid.conf, woth 15 lines of actual config which is below default config recommends.

But hardly you can brake something woth this config in order to get slow uploads. If your SQUID server has 5Mbps upload speed test then it is 5Mbps for squid users also.

Ok, so you say when you BYPASS the squid server, it's faster? Yeah, that seems exactly right...so again, what's the problem?? If your squid server is limiting the speeds, then it's doing EXACTLY what you told it to do, which means there is no problem.

As a test, have you tried to put a Linux workstation 'direct', to see how fast it goes??

no i tested at userend.

...which STILL TELLS US NOTHING. What do you mean by this? Having to guess at EVERYTHING is tiresome...again, unless you provide DETAILS and ask a clear question, there is not much point in posting.

downloading speed too slow
 

hello i am using squid 3 on CentOs 5.6 and i have wan ip and download speed is 10mbps when i am using his ip direct on xp or win7 macine but when i make CentOs squid proxy server or transparent server my clients get too slow download speed like 100kbps but for smaller files as well larger one also my configuraion is too simple no delay pools just i have masquerade and cache_mem 20mb
eth0=wan
eth1=lan
iptables are as

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 3128

single acl for lan i-e
acl my-net src 192.168.0.0/24
http_access allow my-net

visible_hostname varan

http_port 192.168.0.1:3128 transparent

what should i do next so i get rid of clients complaint of slow download speed.

What you need to do first is open your own thread for your own question, and not hijack someone elses. Please read the LQ Rules. Second, if you only have 10MB/s and you're SHARING that, you will quite OBVIOUSLY have slower speed, since that one connection is being used for SEVERAL people. And please see what we asked the OP of this thread about providing DETAILS...you say NOTHING about your network environment, type of hardware, machine, NIC's being used, etc.
