How to Convert VA to Watts

VA to Watts


How to convert apparent power in volt-amps (VA) to real power in watts (W).

VA to watts calculation formula

The real power P in watts (W) is equal to the apparent power S in volt-amps (VA), times the power factor PF:

P(W) =  S(VA) × PF

So watts are equal to volt-amps times the power factor.

watts = volt-amps × PF

or

W = VA × PF

SQUID PROXY SETTINGS

General Settings are now done. So save’ em and move on to the Cache Management Tab.

We need to do some math before we determine cache size values. The temptation, since we have gobs of our 250 GB disk available, is to use a large chunk for web caching. The thing is that Squid uses an in-memory
index to address the cache. So it is best to balance memory against disk cache size.

The Squid User Guide recommends 5 MB of memory for every Gigabyte of disk cache (you don’t want to be thrashing, incurring a high swap rate). So determine how many megabytes of memory you have to spare for caching, divide that by 5, and you have the number of Gigabytes you should allocate to your cache.

Pfsense Throttling By Ip Base

pfSense


Limit Bandwidth Usage By IP On Your Lan

This is a guide to Limit Users by Priority on a 8 Mbit/s line.

Notes:

Note 1: This technique uses a HARD limit on groups of IP addresses.  If you follow this definitive guide, you will be able to limit groups of IP addresses to a maximum specified bandwidth.

Note 2: I am using 3 groups to specify hard-limits, namely LOW, MEDIUM and HIGH with allocated bandwidth of 1, 1.5 and 3Mbit/s respectively.  URGENT: If you want to use a fraction i.e.: 1.5Mbit/s use 1500Kbit/s!
