Pinetab Mobian optimization

[tomoqv]

I am starting thread for tips about optimizing Mobian on the Pinetab. As built-in RAM is limited and the Pinetab seems to suffer significantly from it, I would like to find the settings that yields the best possible performance for running firefox, geary and other programs and apps.

Here are my current settings, which I think give some performance improvements although my Pinetab is quite laggy still at times and even freezes occassionally.

/etc/default/zramswap

Code:

PERCENT=100
#SIZE=512
PRIORITY=100
CORES=1

/etc/sysctl.conf

Code:

vm.vfs_cache_pressure=500
vm.swappiness=100
vm.dirty_background_ratio=1
vm.dirty_ratio=50

Please tell me if these settings are of any help to you or if you have other settings that makes the Pinetab faster and more responsive.

Here are some memory stats with the above settings:

After a fresh reboot:

Code:

~$ free -h
              total        used        free      shared  buff/cache  available
Mem:          1,9Gi      795Mi      443Mi        56Mi      690Mi      938Mi
Swap:        1,9Gi          0B      1,9Gi

With firefox running:

Code:

~$ free -h
              total        used        free      shared  buff/cache  available
Mem:          1,9Gi      1,3Gi        63Mi      161Mi      551Mi      319Mi
Swap:        1,9Gi        16Mi      1,9Gi

With firefox and geary running:

Code:

~$ free -h
              total        used        free      shared  buff/cache  available
Mem:          1,9Gi      1,3Gi        66Mi      180Mi      542Mi      294Mi
Swap:        1,9Gi      330Mi      1,6Gi
