RE: [squid-users] cache hit and byte hit ratio
Thanks Chris I increased my maximum_object size to 128mb ( earlier it was 32 MB ) And I changes replacement policy also. I can see my byte hit ratio has increased to 20-25 %. How can I further increase it. What other parameter I must consider. I have noticed lot of traffic for windows update. Is there any way to cache that. I tried using refresh pattern for same but I still get TCP_MISS.

[squid-users] Balasan: Re: [squid-users] cache hit and byte hit ratio
maybe you should set reload_into_ims on, and more extreme configuration is to set all cacheable file to ignore-reload. for example: refresh_pattern -i \.jpg$ 10080 100% 43200 reload-into-ims refresh_pattern -i \.swf$ 10080 100% 43200 ignore-reload refresh_pattern . 10 50% 43200 reload-into-ims but i suggest you to block banners rather than modifying refresh_pattern regards, [EMAIL PROTECTED] --- Christoph Haas <[EMAIL PROTECTED]> menulis: > On Mon, Sep 05, 2005 at 12:21:35PM +0100, > [EMAIL PROTECTED] wrote: > > I am running squid 2.5.10 stable. > > I noticed cache hit ratio on my server is 30 % but > byte hit ratio is > > less than 15 %. > > How can I increase byte hit ratio.

Then you would have 50% cache hit ratio but perhaps only 0.0001% byte hit ratio. Not every object is cachable. Just use a large disk and if you have multiple proxys then establish a sibling relationship between them. There's not much else you can do. "Tweaking" refresh times surely breaks more applications than it helps you. And if you want to save 95% bandwidth: block porn sites. ;) Regards Christoph -- ~ ~ ~ ".signature" [Modified] 3 lines --100%--3,41 All

I didn't understand this part. How firewall will increase cache byte hit ratio?

[squid-users] cache hit and byte hit ratio
Hi I am running squid 2.5.10 stable. I noticed cache hit ratio on my server is 30 % but byte hit ratio is less than 15 %. How can I increase byte hit ratio. I want to save BW. I am not able to save much. Thanks LK Disclaimer The information contained in this e-mail, any attached files, and response threads are confidential and may be legally privileged.
