Thank you Christian, as always you are coloring the Zentyal forum.
Yes, I read the topic you linked to. But the topic starter has not implemented any tweaks to Squid.conf or improved the filesystem.
Neither does he inform about the hardware he uses.
I found one important tweak, "mem_cache" that is very important for Squid performance. As far as the user count, if claudiompjr has 200 users
he could take advantage implementing Squid.
I just think the tweaks he made are not the right ones, but before giving advice I have to test it myself.
That said, I run Zentyal 3.0.9 and Squid at a clients shop, few users so not really groundbreaking but it is good to gather information and to learn.
Until now I haven't run in to serious issues, but I agree with you Christian that Zentyal 3.x is not to be considered trouble free at this point.
So...The logical question for the Zentyal team, will Squid 3.x be made available for Zentyal 2.2.7 also or is it exclusively for 3.x?
I'm thinking to go this way: Buy two SSD drives. One small SLC /eMLC based drive for /var. Frequent writes from logging, Squid cache and www dir.
It should be around 20GB maximum.
The other drive could be a normal SSD drive for more static data so it will last a bit longer.
In that way I could optimize the /var to my likings, and two SSD will still consume less power and generate less heat than my raptor 10k.
Cheers.
