lldb remote debug takes too much time to pull denpendency lib from the host-machine

[Lioncky]

I mean gdb attach speed is x10 faster than lldb!!! While lldb attach, it load image from the host path. That takes too much time.
the image list show the current image list of attaching process, even if I use usb instead of adb-wifi, it need takes 10+ second to load every image in host-machine path at least. And If I using gdb and attach, it hit the break point immediatly.

These option was I tried to speed up attach but no effect.

            "settings set target.process.stop-on-sharedlibrary-events 0",
            "settings set target.experimental.swift-enable-cxx-interop false",
            "settings set target.inherit-env false",

Yes, that not solve the problem, I think user should not define the path of unused dependency .so file.
For me, only myexe.out is used, other system .so lib should not take much time and no need load on host machine.

So far, I only found launch on target-machine and using process attch command is fastest way to debug, but it can't break at the entry-point.

No matter what option is input, the dependencpy .so lib always load from host machine
like "settings append target.exec-search-paths \"/data/local/tmp:/system/lib:/system/lib64\"",
As long as launch app by using lldb process launch, it load dependency lib from the host and take a lot of time.

if using target create and using --no-dependents it takes more and more but still load from host.

Is it too exaggerated to need to pull over 200+ dependency files from the host each time to debug.
