back to this sensitive topic,
looks like zram solves the issue"
I have wandered into this thread after seeing ric96's recent youtube video referred to above, enttitled
“ Increasing RAM Capacity on Raspberry Pi using zRAM. Does It Work? “
If I understand correctly running the pi with this script or hack enabled has the effect of providing signifigantly more usable ram ( up to 2gb?) albeit at the cost of slightly increased cpu usage . After trying the script for a little while with ric96's easy to follow instructions (even for this linux novitiate) my subjective experience seemed to bear this out. It appeared I could open signifigantly more tabs than usual with some multi-tasking of video and audio. The cpu usage on my pi 2 did appear noticeably higher according to the resource monitor but without too many noticeable adverse effects perhaps running a little more sluggishly (I'm not sure). The pi's temperature did not seem to increase.. Presumably the script would have even more benefit on a pi 3 since it has a little more cpu speed to sacrifice. I have my pi2 overclocked to 1000. Ric96 refers to this script as being a bit of an experiment and indicates it as particulary useful for difficult compiling tasks.
My questions to Ric96 are: does he see this script as useful for web browsing scenarios and general usage? What are the advantages and disadvantages? Can the script be better optimized particulary for web browsing ? Does he plan to further develop, refine or enhance this script or has it already acheieved a level of perfection so beautiful to behold that it cannot possibly be improved? In other words should I keep using it?
Pursuant to an earlier thread:
viewtopic.php?f=63&t=164359&p=1061307&h ... 7#p1061307
I have followed G. Kreidl's advice therein and reduced swapping by setting
Does this setting of swappiness effect the usefulness of this script for better or worse? Should I change the setting? My /etc/dphys-swapfile has been left at the default of 100 meg. Should this be changed? Sorry, if these questions seem elementary or stupid but as noted I am pretty much a novice and am seeing things but through a glass darkly so to speak.
Since this thread is in the off-topic section of the forum how much benefit would I see in web browsing performance by getting a pi 3. My Pi 2 is overclocked arm core gpu etc. I really don't use wireless or bluetooth much and I already have dongles?
