Slow upload files for Wordpress

twest

bippo do you have low IO bandwidth/IOPS? Maybe uploads get throttled if the upload speed is faster than limits to write data to disk.

bippo

twest I made a performance write test and the servers can write at 1.2GB/s.

JohnB

bippo We have 2 separate instances of Enhance on 2 different data centers, and we have the same upload problem on both instances.

Are these VPS servers or what provider are you using?

bippo

JohnB Yes, it's VPS servers hosted on Hetzner and a Swedish data center called GleSYS.

I installed speedtest-cli and on Hetzner we have ₃.5Gbit down and ₃.8Gbit up. On the other datacenter we have around 2Gbit up/down.
I also tried scp to copy a large file from local to one of the servers on Hetzner. It reached about 150mbit just before the copy was completed.

did anyone get any solution for this? i am facing same problem

Re-open this old thread. Someone know what to check? My .ini has both upload_max_filesize and post_max_size at 200MB and my network is gigabit, but my WP is uploading to 1mb/s. Openlitespeed here.

cPFence Thank you. I had that problem when i upgraded to v12 and fixed weeks ago, now i already have those configurations. Upload works, is just slow!

I’d try resetting the .htaccess, disabling plugins, clearing cache, restarting PHP, restarting OLS, resetting wp-config.php, and double-checking the IO limits in the plan or any overrides for the site.

Finally, if all that fails, I’d install a fresh test WordPress site to a temp path and test the upload there.

Vendoz

cPFence Yeah before writing here, i did an upload test with a fresh wp, just with wp-all import to upload a simple 2GB website backup, and it is indeed slow, I will do further checks.

One more time, I tested this issue.
Only settings on the server where the website is located affect on behaviour - so when I use:

Apache - upload 2MB max files (without mod security)
Openlitespeed - upload bigger files with speed _2MB/s, sometimes restricts speed to 600KB/s, sometimes it works like Apache and doesn't upload files more than 2MB, so behaviour is different.
NGINX - upload _6Mb/s and any problems except my provider's internet speed 🙂

cPFence - guys, maybe your team can help with this.

I have the same issue, tried litespeed and Apache, with and without Mod Security.
The issue is that I transferred dev websites on staging domain which is hosted by Enhance DNS then upload some files from updraft backups and upload stopped work, so it started to upload 2mb and stop, then I globally added upload max size etc... after some time I thought that it helped but it was only for one dev website and then all other again stop upload files more then 2mb as via wordpress as from panel filemanager.

Next day (like today) I continue and looks like it start work but the speed is like 200-500kb/s

I want to mention that via FTP everything is working ok and the speed is 6-8mb/s.

I connected to the server via SSH and checked global php settings and I see only one relation that upload_max_filesize and post_max_size are 2mb but in any case here is php version 8.1 and website working on 8.3, I'm not sure that its somehow related to the issue but it is.

In total, IDK how to resolve this issue, but it's uncomfortable to use the website with these restrictions. The behavior is very similar to some restrictions and I didn't find a way to control that.

I used the Owner user to create this staging website, so there are no package restrictions + I have only one test package where all settings around files and data transfer are unlimited.

Maybe someone has already resolved that.

ferrokot I have the same problem, for some time now...
Upload through file manager tops at around 600KBps. FTP or SCP goes up to 30MBps.

@Adam can you please help?

For the Control Panel server, Did you try to switch the Webserver to NGINX ? And give it another try.

ferrokot

I have tried only Apache and OpenLiteSpeed as for control panel as for the server where the website is located. After my tests I see that main server for CP not relared for that issue because when I uploaded from Filemanager or via the WordPress admin panel, I had the same small speed or the same behaviour when it's not upload more then 2mb for both methods.... and WP admin pannel dont have relations with Control Panel server . So the problem should be on the server where the website is located.

adil

PDudeP

adil several months ago that did the trick. But now, it doesn't seem to be related.
I tried, though.

adil

ferrokot

Yes I know, I just replied to @PDudeP issue because I had the same one before and NGINX works better for the Control Panel server.

As for your issue, sorry, didn't have any suggestion rather than to open a support ticket maybe Adam can help narrow down the cause of the issue.

tried a couple of uploads/downloads.
using panel file manager, scp and ftp on both a system website on control panel server and on a client website on a webserver.
both small test servers at hetzner.. 2cpu 4gb.. nginx as webserver on both

used the same file each time (440Mb)

scp uploaded file to each server in around 10 seconds... sshd rose to around 30% cpu, scp to around 10%
upload took around 10 seconds
ftp (only to ciient website, ftp not available on system website)

during upload pure-ftpd spiked to around 33%cpu then steady around 15%
upload took around 30 seconds
download took around 30 seconds pure-ftpd around 3% cpu

scp, upload and download took around 30 seconds
sshd around 30%cpu scp around 10% on upload, sshd around 8% scp around 3% on download

enhance file manager, upload takes several minutes
filerd constant around 5% cpu
download takes around 30 seconds, filerd initially spikes to around 60% cpu then drops to negligible and stays there.
i assume the download is initially started by filerd and then handed off to nginx...

ferrokot

nhybgtvfr so what to do? Your suggestion is to use Nginx? from my side it's 100% not related with CPU usage.
Thanks for the tests, but how can it resolve the problem? There is no problem with FTP.

I didn't test with nginx because I'm not going to use it.

Still waiting @Adam response, maybe you can suggest something
Will appreciate that a lot
thanks everybody

It’s a long-standing problem with all file managers across different panels. They’ve never been reliable for large file transfers and are really only meant for small to medium-sized files.

Even cPanel has had the same issue for 11 years and still hasn’t fixed it:

If you’ve got a 1 Gbps connection, you can get away with it, but otherwise it’s better to stick with SSH or SFTP, or spin up a temporary HTTP link with a unique filename if you need to serve big files.

Thanks for the reply, but the problem is not in the file manager, it's a global problem. I tried to upload files for all-in-one, or for updraft, also the problem is when the client tries to upload an image more than 2MB or PDF file for 10-20mb.
All of I mentioned above isnt related with Enhance filemanager... it's related with wordpress admin pannel functionality.

So also if clients website have a form with attachment for CV as example it start to be a problem too... and one way to resolve this it's using NGINX... so it's a little strange and I think that it should be fixed, maybe I did somehting wrong, but I'm new and have a basic setup and dont use any custom settings, customisations, scurity things etc.
