The local Disk cache only use 10M, is that normal and my cache working well?

Hi ,

I am using Squid Proxy and Enable the local Cache + SSL Inspection to try improving the slow ADSL bandwidth performance.

My cache setting is as below:

Cache information from squid:

Hits as % of all requests:	5min: 5.1%, 60min: 9.9%
Hits as % of bytes sent:	5min: 4.6%, 60min: 10.2%
Memory hits as % of hit requests:	5min: 7.9%, 60min: 2.0%
Disk hits as % of hit requests:	5min: 53.9%, 60min: 57.5%
Storage Swap size:	602908 KB
Storage Swap capacity:	 5.9% used, 94.1% free
Storage Mem size:	102300 KB
Storage Mem capacity:	 9.8% used, 90.2% free
Mean Object Size:	28.12 KB

The Custom refresh_patterns configured as:

refresh_pattern ^ftp: 1440 20% 10080

refresh_pattern ^gopher: 1440 0% 1440

refresh_pattern -i .(gif|png|jpg|jpeg|ico)$ 10080 90% 43200 override-expire ignore-no-cache ignore-no-store ignore-private

refresh_pattern -i .(iso|avi|wav|mp3|mp4|mpeg|swf|flv|x-flv)$ 43200 90% 432000 override-expire ignore-no-cache ignore-no-store ignore-private

refresh_pattern -i .(deb|rpm|exe|zip|tar|tgz|ram|rar|bin|ppt|doc|tiff)$ 10080 90% 43200 override-expire ignore-no-cache ignore-no-store ignore-private

refresh_pattern -i .index.(html|htm)$ 0 40% 10080

refresh_pattern -i .(html|htm|css|js)$ 1440 40% 40320

refresh_pattern . 0 40% 40320

However, I see my /var/cache still using only 10M for this case, it that normal?

You asked for :

That's 10Gto me.

@bluegrass-168 said in The local Disk cache only use 10M, is that normal and my cache working well?:

Don't use the image as an info source.
It's a nice GUI image, and doesn't show your /var/squid/cache/ content.

Do the real-man thing : go console (or the modern-man thing : fire up a sftp (like WINscp sp yo can browse the pfSense file system))

Btw : your system has (only) 23G ... what disk are you using ?

Also : you will discover something : most sites (== pages) you visit use branded file names, that is, every time you visit the page, it has another file name, another creation date and of course a different content. So, the file you cache will nearly never be the one you can re use again on a later visit.
Caching, IMHO, was a good thing back in the plain http web site days. These are over.

If this :

Hits as % of all requests:	5min: 5.1%, 60min: 9.9%
Hits as % of bytes sent:	5min: 4.6%, 60min: 10.2%

is what I think it is, that's actually quiet good
Again : IMHO.

@gertjan

Ar....haha

The local cache is located at
/var/squid/cache/
but not
/var/cache

I know the reason now.

Btw : your system has (only) 23G ... what disk are you using ?

I install the Pfsense on my Synology as a VM. That is crazy, I know. haha. I just want the Proxy feature, I think still good?

BTW, Do you manipulate on "refresh_pattern" as well?
I also need some helps here.

Actually, I want to cache every thing as I can.
Should I just keep below and remove all the other patterns?

refresh_pattern . 1440 20% 14400

@bluegrass-168 use https://github.com/mmd123/squid-cache-dynamic_refresh-list for refresh_pattern (note you can always submit pull requests to improve the list).

"Actually, I want to cache every thing as I can."
In order to cache https you need to use SSL Man In the Middle Filtering

However you do not want to mitm everything as it breaks way too many things. So use
Custom Options (SSL/MITM)

than add something like this

acl step1 at_step SslBump1
acl monitoredSites ssl::server_name "/home/bumpsites.txt"
ssl_bump bump monitoredSites
ssl_bump peek step1
ssl_bump splice all

and at the file location /home/bumpsites.tx add your list of sites you want to decrypt to cache.
Here is a list that i made (NOTE: i have not tested all domains, so if some have issues remove them, eg things like ubisoft.com)
bumpsites.txt

What i did was i went to winget https://github.com/microsoft/winget-pkgs and got a list of the download domains.

This should also cache steam and epic games.

Good luck
