Looks like we overlooked the cache mem part. It looks fine. Let me also
correct that load increased once and we were using SquidGuard that time.
Sorry for the confusion.
total used free shared buffers
cached
Mem: 3791 3068 723 0 640 2001
-/+ buffers/cache: 425 3365
Swap: 4000 0 4000
Total: 7791 3068 4723
Do suggest if you see any scope for improvement in memory/cache_dir/other
settings. We expect upto 50 simultaneous users using squid at any point of
time.
Thank you.
