PfSense 2.2.3 - Internet is very slow via Squid3

Mr. Jingles

DNS issues can also make squid look slow. Shell in and run:

squidclient -h LAN_IP_Address -p 3128 mgr:info

Then read the report, paying special attention to the Median Service Times section. Look for anything that seems large as compared to the others.

I do not want to hijack this thread, so if I have to create a new thread (similar problem), I will, just let me know :-[

What would you make of this, KOM?

Thank you :P

Everything looks normal. I think your problem is disk-related as you suspected.

gdsnytech

@Mr.:

@jimp:
Some have found that the disk changes we made for sync mode have slowed down squid by default.

If you want to risk the possibility of disk corruption but gain speed, edit the ,sync out of /etc/fstab for the root slice and/or run
mount -o nosync /
My squid3 is not fast either. But I don't like risking disk corruption, possibly destroying pfSense. That is: what are the odds disk corruption will appear, Jim? Relevant variables? A thumb number (0,005% or 60%)?

I have made the change in fstab both for work (two sites) and home setup and it is working fine. Just make the change in fstab and then reboot.

hello
let me explain you this changes for squid caches but i dont use squid for cache contens my config is 0
so can i make this changes ?¿?

Hi!. I'm having this same issue, when the proxy is enabled the webpages takes a lot of time to load and, once loaded it becomes more responsive but, still, is very slow.
I have installed Squid3+SquidGuard Transparent proxy enabled and SSL filtering on. I've disabled squidguard (just to make sure) and the issue keeps there. Then, when I configured the lannet to bypass the proxy, the issue dissapeared so I think I've missed something important with Squid3.
I tried to edit the /etc/fstab from this:

# Device		Mountpoint	FStype	Options		Dump	Pass#
/dev/ufsid/558c431cbd7f951e		/		ufs	rw,sync		1	1
/dev/label/swap0		none		swap	sw		0	0

removing the ,sync so the file now reads:

# Device		Mountpoint	FStype	Options		Dump	Pass#
/dev/ufsid/558c431cbd7f951e		/		ufs	rw		1	1
/dev/label/swap0		none		swap	sw		0	0

I ran the command

mount -o nosync /

and restarted the box…
The issue? still there...
Am I doing something wrong?

Thanks in advance

-------Update------------

I got tired so did a full restauration from a file that I've backed up previously. I didn't knew what was causing my trouble, but now it is gone. I suggest the young adventurers that they do, at leas one time at week, a full backup of their configurations so, if they experience some isssue of this kind, have where to "run"... It is easier and faster.

KOM

Did you try my much earlier suggestion of running squidclient and then checking the numbers for outliers?

This might be a bit of a "basic" answer, but to me squid3 was painfully slow when using c-icap antivirus integration.
The clam process just ate my cpu and the sites took ages to load.

In clam's defense my system runs on a VIA C7 1,5Ghz + 512MB ram… getting too old for all of this.

squid3 was painfully slow when using c-icap antivirus integration.

Of course the addition of either ClamAV or HAVP is going to cause a lot of overhead and will slow down everything. I've always recommended using a client-based AV instead of having it on the firewall.

Hmm, When I ran

squidclient -h 192.168.1.1 -p 3128 mgr:info

I got

I setup squid today and I believe I am experiencing this issue as well. I'll try that fstab thing. I did notice that using "links" in shell on pfSense seemed to have the same slow download speed that I have when going through squid, in case that helps any.

KOM

aGeekHere, are you sure you got it right? You get that HTML spew when there is an error.

aGeekHere, are you sure you got it right? You get that HTML spew when there is an error.

Oh no, Well I ssh in and ran

squidclient -h 192.168.1.1 -p 3128 mgr:info

In the root folder.

Ok trouble shooting time, where do I start?

KOM

On Squid's config page, look for External cache-managers and set it to 127.0.0.1, 192.168.1.1. Save and try again.

When I add 127.0.0.1;192.168.1.1 to External cache-managers I now get.

Weird. Check your System logs and squid logs. I haven't seen that error before.

Ok some logs
