Take loog time when first time open java file

[wsdjeg]

I am not sure why it take too long time when first time I open a java file, you can hava a look at

https://asciinema.org/a/3qf5mv191b6o0oz74nxu45sdj

[wsdjeg]

here about 1s, when I type enter in ctrlp buffer, but sometime it need more than 10s.

[artur-shaik]

With clean vimrc the same?

[wsdjeg]

yes, run vimtest in the root of this plugin, vimtest means

alias vim='nvim'
alias vimtest='vim -u NORC --cmd "exe '\''set rtp+='\'' . getcwd()"'

then run

:e libs/javavi/src/main/java/kg/ash/javavi/Javavi.java

it need about 5s.

[artur-shaik]

I know some start up delay issues exists, such:

• cache read or scan sources and libraries;
• too big source file for viml java-parser.

That's why we still have limitations section in readme.

So, this is hard to say what exactly influence on your issue. It would be great if you can find those narrow places. I think 10 seconds is too much.

[wsdjeg]

I will look into it later.

[artur-shaik]

Did I understand right that 242_GetServerAppVersion take almost 11 seconds?

[wsdjeg]

yes, I think so,

Hm, that strange. Made the same, here my results:

What if you run:

java -cp javavi/target/classes:javavi_log4j-api.jar:javavi_log4j-core.jar:javaparser.jar kg.ash.javavi.Javavi -version

From vim-javacomplete2/libs directory?

[wsdjeg]

it take me 3s, I think maybe it is due to my pc is too old.

[artur-shaik]

What cpu you have? And what java version?

[wsdjeg]

I use time java -cp javavi/target/classes:javavi_log4j-api.jar:javavi_log4j-core.jar:javaparser.jar kg.ash.javavi.Javavi -version

real       0m1.940s
user       0m2.527s
sys    0m1.107s

[wsdjeg]

I use open jdk 8, and my cpu is i5, but my pc is 6 years old, sorry for this issue.

[artur-shaik]

I use i5, too. I think it's due some java slow start issues. And by the way, my java is oracle hotspot.

[wsdjeg]

yeah, I will try to install oracle jdk. thanks!
