Android Question B4a v8.00 is slow

[ilan]

i noticed since the last update that b4a runs very slow while typing. i also disabled implicit Auto Completion but still, it runs slow.
opening Task Manager i can see why:

b4a is using about 2GB of my ram. most goes to Java(TM) Platform SE binary.

should it be like that? can i do something to improve it? (except of buying a new laptop)

thanx, ilan

Add 2gb ram on your pc

This is not related to B4A version. The memory is consumed by the optimized dexer. I guess that your project uses Google Play Services which is a relatively large library.

If you think that it slows down the PC then you have two options:
1. Disable the optimized dexer.
2. Increase MaxRamForDex.

i use Firebase Admob and notification in my project so does it mean i use Google Play Service?

i will try to increase the MaxRamForDex because i have no idea what will it happen if i disable optimized dexer

btw i have 8GB ram i guess it is better to buy another 8GB for my laptop right?

yes

if i disable optimized dexer

the compilationstep needs a bit longer.

 

[ilan]

the compilationstep needs a bit longer.

only that?? anything else will stay the same?

Dex (Dalvik Executable) serves to optimize data management in with Dalvik (Virtual Machine) now from version 5+ we use ART as runtime VM

 

[DonManfred]

i think yes

用于优化Dalvik（虚拟机）的数据管理，现在我们使用ART作为运行时VM

now everything is clear

i think i will increase the ram until i buy another 8gb ram for my 5years old laptop that i love so much

btw since yesterday i noticed that the forum is very slow, it takes few seconds until the post i send is accepted and surfing here takes now time to load pages, but thats a topic for the forum discussion and not for here. maybe some background service is done by erel

wow after setting optimized dexer to false b4a is using 90% less memory
it takes maybe x1.5 to x2.0 longer to compile but 90% less memory, that is really a lot!!

For my larger pjt I don't have such a memory usage:
I have 8Gb as well... also editing program is fast on new B4A 8.0

 

[tigrot]

Since you have 40% memory left you are sure that adding RAM won't encrease performances.
I'm experiencing general Internet slow down in the last days. I have 50Mb Fiber Optics, but also this forum seems as slow as me!

 

[Star-Dust]

I have a 50in of 256k memory banks for 80386 if you can mount it on your, i gift you

PS the forum goes slow to that to me ... it's not a ram problem

yes i understand that it is not a ram problem but why is it so so slow
everything else works fine (youtube, news, facebook,...)

 

[Star-Dust]

I suppose .. but I'm not sure. Better to ask Erel
