Deleting many files (n=500) using the web interface seems too slow

[nikslor]

Describe the bug

I stumbled upon this, when cloning my home dir to oCIS. After upload finished I had a large list of empty files in oCIS (may be related to owncloud/ocis#2609) and I wanted to get rid of them. I (manually) selected all empty files and deleted them through the web interface. It took minutes until the action was finished which I'd expect to happen faster. I think there is something fishy when deleting files - not sure if it's a bug, but it's reproducible slow (IMHO).
I sometimes also see a browser redirect to the root folder after deleting finished. This should IMHO not happen and may underline, that there's something not 100% right here. It most of the time happens, when I have 1000 files and delete 500 of those. (I'm happy to create a separate bug if you think it's worth it).

I think it's worth checking, it's not of high priority.

Steps to reproduce

Steps to reproduce the behavior:

1. Create a local folder with e.g. 1000 files: $ for i in $(seq 1 1000); do touch "$i.txt" && echo $i > "$i.txt" ; done
2. Upload the folder to oCIS (e.g. using the web interface)
3. Navigate into the folder and list e.g. 500 files
4. Select all files
5. Click/tap delete

Expected behavior

Deleting should not be much slower than uploading there should not be a redirect (to the root folder) after deleting.

Actual behavior

Deleting takes very long (IMHO), while uploading the 1000 files (using "upload folder" through the web interface) takes only ~50s, deleting 500 files takes around 12min. The HTTP DELETE requests as such are fired within seconds and I also see those request in the log on the server side immediately; it's unclear to me if the actual action takes so long or it's just the web interface not being updated correctly.

Setup

I use oCIS 1.15.0 on Linux x64 with a POSIX FS as backend and local users (not OICD, LDAP, ..), I start oCIS like this:

OCIS_BASE_DATA_PATH=/var/lib/ocis ACCOUNTS_DEMO_USERS_AND_GROUPS=false PROXY_HTTP_ADDR=0.0.0.0:443 OCIS_URL=https://storage.0x17.ch PROXY_TRANSPORT_TLS_KEY=./certs/fullchain.pem PROXY_TRANSPORT_TLS_CERT=./certs/cert.pem PROXY_ENABLE_BASIC_AUTH=true ./ocis server

As web browser I use Firefox 94 and Chrome 94 - both show +/- the same behavior.

Please let me know if you need more information, happy to provide them.

Thanks for pointing this one out, I moved it to the web issue tracker since I'm fairly confident it's a frontend topic

Has been fixed via #7357. The future holds an even better approach with async delete, but for now it does the job in a reasonable time.
