Mail App Email Loading Slow

💻 Development
#1

Loading emails in the nextcloud mail app is very slow for me (10s+ on an average email), removing html and the encrypted elements from the vues makes it like 8 seconds faster but going with just the MessagePlainTextBody causes bad formatting.

Request Time (Never opened & Average length email):

  • thread - 94 ms
  • body - 2.69 s
  • html - 4.01 s
  • flags - 3.68 s

This is using googles SMTP and IMAP with their XOAuth as well, which should be a lot faster than this.

SMTP: smtp.gmail.com
IMAP: imap.gmail.com

do you have a slow internet connection?

#3

I’ve tested it on multiple connections, the current one being 400 down and 30 up.

#4

what version of Mail do you use? at least loading the thread was recently improved.

Also how big are you oc_mail_* tables?
