I agree that there is an issue that needs to be resolved though believe that will be easier said than done as having run similar tests, I do not experience the performance difference with eMC, however, accept that others do; this is why I believe any issue will be difficult to resolve.
In all instances my attachment of 5mb was there almost instantly.
I used Surfshark VPN with antivirus to slow things down.

Pinging on this one…as I am another user with painfully slow attachments. I have been getting some mid-sized PDFs lately from a vendor (between 10-20MB in size), and they are awful to sit and wait while they download. If I use Outlook, they download and open immediately. PC, Pro User, on Windows 11 latest version.
You have to read through these threads to find solutions
In a July 2023 post in one of these threads, Gary recommended adding a string parameter to the advanced options box.
He said this downloads attachments in a way that is faster but less reliable, and so it should only be used if you were having a problem.
In a September 2023 post, he pointed out the checkboxes for downloading attachments in Accounts > IMAP > Sync Options.
My understanding is that this basically pre-downloads all the attachments you get locally. (It would be great if those messages and their attachments go back to the server when you move them out of the inbox, but IDK.)
So, those are the two fixes on offer now in one post. I tested both of them and they worked.
I have tried the setting and also have made the changes to the account settings; attachment download speed is still very slow. We are using the default Windows antivirus, have a gigabit connection and no VPN.
We have to go to the gmail web page and download attachments from there. They come very fast.
Any solution on the horizon? This is ridiculous. The software looks very promising, but there’s no way I’m paying two cents for it with this issue on board. An absolute dealbreaker. This topic dates back to a YEAR ago and the problem apparently persists.
That raw download option @Gary advised is now also available to enable in V10 Beta for Desktop and Mobile app “without adding a parameter string” as in the Gmail IMAP example below.
For Exchange it may be a slow connection to the server, or just a slow server. There is something you can try though. It won’t speed up the connection or server, but it will cache attachments when they arrive so when you later click on them, they should open immediately. Go to Menu > Accounts and click on the Exchange tab for the account. Scroll down to Sync Options, tick both of them, and click on Save & Close.
Also been having this issue for a while. Thought it was just my laptop acting up, but have now tried it on multiple Windows devices, and have the same result. A PDF file attachment of a few megabytes takes FOREVER to load, and renders the rest of the email application useless during this loading time. Needs to be resolved, its the main thing letting down emClient at the moment. None of the other email apps I’ve used have this problem (thunderbird/outlook) so surely this can be resolved at the software level.
