Slowdown and crash when uploading files to Huawei P30 Lite
When uploading a lot of files to huawei p30 lite android-file-transfer GUI application starts slowing down, eventually hitting timeouts and crashing. It starts with approximately 20MB/s write speed and eventually drops to 6MB/s, and after some more time it crashes.
Reproduces both on 4.2 and current master (commit 4687cf4)

It looks like AFTL struggles to create ObjectInfo in time :thinking:
If you're able to build it from source, could you try replacing in mtp/ptp/Session.cpp:293:
Send(OperationRequest(OperationCode::SendObjectInfo, transaction.Id, storageId.Id, parentObject.Id));
with
Send(OperationRequest(OperationCode::SendObjectInfo, transaction.Id, storageId.Id, parentObject.Id), LongTimeout);
It didn't help to fix this issue for me. Crash looks same, but maybe it happens just a bit later.

Thanks, how many files do you upload? what are their sizes? I'll try to recreate on one of the slower devices.
129 files, 1 directory with 3 subdirectories, total size 2.7GB. File sizes vary from 2MB up to 70MB.
What are file types? Pictures or just binary files? Why I'm asking is that maybe it tries to generate thumbnail entry along with file entry.
Also what is your android version and host linux kernel version please?
Files are flac (corrected: music with lossless compression), except for 2 jpg pictures (200 KB and 1.5MB) and 1 pdf file (33MB).
Android 10 (EMUI 10.0.0.465, kernel 4.14.116), host linux kernel sys-kernel/gentoo-sources-5.10.52.
