Problem with image uploading

[korosa]

Please help me solve the problem. Images and videos take a very long time to process when uploading to the site. The upload to S3 itself is fast, but the "processing" takes a long time — around 20 seconds per image or video. As a result, uploading a folder with around 100 files takes a lot of time.

It's important to note that the upload directly to the server is fast. What could be the issue? I’ve tried different S3 services, and the problem doesn’t seem to be related to that.

Processing doesn't take that long, check if you have a proxy without a cap on post body max size.

When using a proxy (for example nginx) you may configure a body max size which when unlimited cause the connection to keep waiting for several seconds.

Thank you for your response. However, I'm using Apache, so this probably isn't suitable for me. Could you suggest any other options? Thx

In that context the most expensive CPU call is the hashing function on the uploaded file, which up to 4.2.5 uses md5 (and it does it twice). There's an RFC for upgrading to xxh64, which will be merged in 4.3.0.

md5 hashing is only a concern for files of certain size (64 MB up?), for small files it should be instant. You should also check the network responses.

You could try using xrDebug to determine where it goes slow.

// <actual code>
xr(__LINE__);
// <actual code>

By adding xr(__LINE__) you will get the line in the debugger plus its time, by doing this you can label the code at different parts and determine how long does it take to get there by simply running Chevereto.
