#ROCKETCHAT CNAT UPLOAD HOW TO#
So I guess I need to figure out how to build rocket.chat to modify this properly but that will have to be for another day.Advanced search modifiers: Slack has advanced search modifiers that help you get anything you need by merely searching for the word or quote, just like you make a Google search.
#ROCKETCHAT CNAT UPLOAD CODE#
I found it in the compiled app.js on the server but changing it and restarting everything didnt seem to change anything I guess the client code is compiled elsewhere cuz trying to grep -r for it makes it explode with minified one-line code. 1MB for nginx or 50MB for cloudflare) and it’ll use just one request if the file is smaller, or split it into chunks if larger, which is actually useful in this case. So I think I can just disable adaptive thing as it doesn’t seem to help at all and set the chunk size to whatever is the highest upload limit for the gateways (i.e.
Ok I found that rocket.chat uses this for uploads and the uploader can be configured with custom chunk sizes as well as disabling adaptive mode which will make chunks large enough to upload at 80% of bandwidth up to a certain chunk size limit, or whateverĪnd this is the only use of UploadFS.Uploader i’ve found in rocket chat codebase using github search and it doesn’t specify anything so looking in the code, the default chunk size is 32KiB and default max size for adaptive is 4K(i?)B (4 * 1024 * 1000). Using default gridfs file store i also tried FileSystem store but it uploaded at a similar speed, although i didn’t look at networking log until after reverting that.
#ROCKETCHAT CNAT UPLOAD MANUAL#
Deployment Method: manual installation using systemd.Operating System: Debian 9 container on Ubuntu 18.04 host.Is there a way to increase the size of the chunks? It seems to upload in chunks of about 25KB, which is really small increasing this would speed up uploads dramatically. Why in the hell does it do this?! It’s incredibly inefficient and causes file uploads to be super slow, especially for those with high latency (my ping to the server is about 170ms as it’s on the other side of the planet). For example a 100KiB file (dd’d from /dev/zero) takes four requests to upload! And a 6.05mb jpeg took about 160 requets to upload!! And each request takes around 300ms before the next one will be sent, causing the upload to take a stupidly long time. Apparently the files are uploaded via many small sequential POST requests. So we’ve been having an issue where file uploads are super slow and I found out why.
