Thanks for your answer

Actually 25 Gb
I tried different values, but I guess no matter, the problem is that the squid limit is only 50% of ram

More I increase vm.swappiness more I swap and more I have problems, but I will try your value

Maybe I misunderstand your point, but when I reduce cache_mem yes there is no problem but Squid uses only 20/30 Go Max
With cache_men 15 Gb squid eats 36 % of memory
Htop and htops reports 30 Go of free memory
total used free shared buffers cached
Mem: 63G 62G 425M 122M 1,7G 27G
-/+ buffers/cache: 33G 30G
Swap: 1,9G 102M 1,8G
All my RAM is consumed by cache/buffers and seems not be freed when it is needed by Squid
