It should depend on what you're doing. Have a look at the sizing guide.

what is your environment?  some more details will help get you better answers.

I think this is old document

Do you have new one? For SG series?

As you can see:

Really only 35-50 users???

There are Dual-Core processor and 8GB RAM - how could be only 35-50 users?

Firewall, maximum value 11,000 MBit/s and only 35-50 users HOW?????

Hi Roman,

The best place to find that answer will be to contact Sophos Pre-Sales or contact the nearest Sophos Partner.

Thanks

I asked here BECAUSE they told me that

SG210 performance only 35-50

I can't believe it......

AGAIN.  give us details about your environment.  Some of here(myself included) are hardware specialists and can see beyond the raw numbers and know enough about the underlying hardware to give you better answers that simply following the sizing guide.  Trust me,  that guide is just that..a guide.  Sometimes you can handle more users per model..sometimes less...it all depends on your environment.  So give us details about your environment..number of users, which features of the utm you want to use..your wan and lan speeds...etc etc etc.  

I have put a utm 110 in a 25 person environment and had it survive..yet i can personally strangle a  SG115 here in my 5 person environment just due to our traffic and usage.  I can actually max out an SG135 without trying too hard.  A SG210 would hang here...barely.  That is why I currently run my SG series UTM as a virtual machine backed by 4 x Xeon 3.0 GHZ cpus with 8 gigs of ram...just to keep up with my usage...:)
