How much AC power do they use?
Curious if anyone has data/opinions on the best ways to keep my energy use down: should I run my ibook g4 on AC power with battery installed or with it removed? should I keep using the old worn-out battery or buy a new one even though I'm usually at home/plugged in? thanks. legolam.
HI,
Keep the battery installed so it stays charged. I finally bit the bullet and purchased a new battery for my iBookG4 and am glad I did as the old one lasted about 15 minutes without A/C power. Also, in System Preferences/Energy Saver, select the preferences that best fit your battery use.

Is there a app that will tell all apps that are running and possibly how much battery power they use?
You don't need an app to do this. Here's how you get the battery info. Go to Settings>More>Battery. This will show you all the active apps and their individual battery usage.

I may have gone overboard in the creation of Tab Groups. I say this because now my system is beginning to act a bit sluggish. I created 7 groups, two of which have 9 or 10 tabs. Should I pull back on the number of groups I create (as well as how many tab are located within each group). That is: How much RAM do tab groups use. How can I calibrate or understand the trade off between these markers and the amount of RAM they use?
You can see the memory usage on the about:memory page.
You can open about: pages via the location bar like you open a website. -

How much data does Apple TV use?
I am experiencing a large amount of data usage and cannot determine what the culprit is. I am approaching my cap of data allowance on a regular basis. Does anyone know how much data the Apple TV uses? I realize it depends on what you are streaming. I primarily stream Netflix (set on the lowest data rate)
ThanksI found this answer on NetFlix's blog sometime last year:
In the USA you have 3 video quality options: good quality, better quality, and best quality. Here is how much bandwidth they each use:
Good quality (up to 0.3 GB per hour)
Better quality (up to 0.7 GB per hour)
Best quality (up to 1 GB per hour, or up to 2.3 GB per hour for HD)
Depending on how many movies you watch this could have a huge impact on your monthly usage...obviously your ISP wants you to watch its own movies. -
How much memory sql server is using
Hi Experts,
I want to know how much of RAM is currently used by sql server.
is there a query for the same?
we are using sql server 2008 R2 SP2 on windows server 2008 R2 with a RAM of 48 GB. min memory as 40, max memory as 43GB.
thanks in advance.
Cheers, Vinod MalloluHi Shanky
Thanks for the info. Perhaps you can clarify something for me on it.
If I run this on one of my production servers:
SELECT object_name, cntr_value MemoryUsageKB, cntr_value/1024 MemoryUsageMB,cntr_value/1024/1024 MemoryUsageGB
FROM sys.dm_os_performance_counters
WHERE counter_name = 'Total Server Memory (KB)';
select physical_memory_in_use_kb,
(physical_memory_in_use_kb/1024) as Phy_mem_MB,
(virtual_address_space_committed_kb/1024) as Total_mem_MB--memory pagefile+physical memory
from sys.dm_os_process_memory
I get this:
object_name
MemoryUsageKB
MemoryUsageMB
MemoryUsageGB
SQLServer:Memory Manager
118488256
115711
112
physical_memory_in_use_kb
Phy_mem_MB
Total_mem_MB
118363564
115589
231792
As I have LPIM enabled I'm surprised at the Total_mem_MB result, page file usage is at 0.09%. Any idea why it would be reported like that?
I'm also surprised that the DMV is reporting a lower number for physical memory usage than the perfmon counter, but I guess they're not measuring the exact same thing.
Edit: Version is SQL 2012 SP2 CU2....should have included that :) -

How much memory are actually being used? db_32k_cache_size
Hi everyone,
Using Oracle 10g on RHEL 5.3.
I've been asked to check how much memory are actually being used by our db cache's. Currently we are using the parameters db_32k_cache_size (user-defined) and db_8k_cache_size (default) both allocated with 12gb. Now I want to know if there is any way to find out how much of the 12gb are actually being used by the cache.
Is this possible?
ThanksThanks Guys,
Okay, so it is using the whole 12gb. I guess the next question would be, is 12gb really needed? You see, we are trying to increase memory where possible as this database has performance issues. Now we are thinking of taking some of the 12gb that is allocated to the 32k cache and assign it to the sga for instance.
Does this make any sense?

How can i determine how much data an app is using
on an iphone5, how can i determine how much data an app is using and or which apps are the biggest data users? do all apps always use wifi when a wifi is connected or do some apps still use cellular data even if wifi is connected?
Try Settings > General > Usage > Storage > check here.
To test if app is using cellular data instead of Wi-Fi, switch Airplane mode: ON and switch Wi-Fi: ON manually. -
