Hi Amos , so you mean that the extra Ram usage is from the instance when it loaded with traffic ?
will that stay even if i have cache men 0 and and cache deny all and disabling all HDD caching ? is there anything can i do ? or leave it s it is ? cheers > On Feb 17, 2018, at 3:20 PM, Amos Jeffries <squ...@treenet.co.nz> wrote: > > On 18/02/18 00:57, --Ahmad-- wrote: >> hi amos >> >> i didnt use the version 3.5.22 >> >> but long time I’m using the 3.5.22 and its fine >> >> the new thing is I’m using like 100 squid instances . >> >> and hourly i have cron to change and update squid >> >> so i just make rec option instead of having session drop . >> >> i don’t have exact mount of statistics to tell you >> >> but say i have 32 G ram >> >> if i run 100 squid instances it take about 16 G ram . > > So that is the amount before much traffic has happened. > > When traffic goes through the proxy Squid gains data which uses more > memory for at least all the purposes listed at > <https://wiki.squid-cache.org/SquidFaq/SquidMemory > <https://wiki.squid-cache.org/SquidFaq/SquidMemory>>. > > >> >> if i keep run the cron hourly by time say daily 12 times ( every 2 hours) >> >> and after 1 week i go to server to see free ram using : >> >> free -m command >> >> i see the free ram be like 5 G free , while I’m supposed to see the free >> as 16 G > > > +10GB for 100 instances means each is on average only using ~100 MB more > than you expected.
