Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
It produced this output: upload speed down from 18Mb/s to 3.4 Mb/s
My web server is (include version):apache2 version 2-.4-.29
The operating system my web server runs on is (include version):Ubuntu Bionic armhf
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know): yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): Cerbot (latest version)
The upload speed on my server has dropped from 18 Mb/s to 3.44
On 6 other devices on the same access point it has remained at 18+
Is there any way I can increase the speed ?
My download speed remains the same (45+)
Do you mean that you are running your own speedtest.net server?
If you’re just using speedtest-cli with one of the existing speedtest.net servers, whether you have any SSL certificate installed doesn’t have any effect on the outcome of test. How your locally installed webserver is configured has zero effect on the test and any changes you noticed would be purely coincidental.
The speed drop is not coincidental. All other devices on my LAN are normal (45+ down 18+ up). Running an older version of my website (without SSL) has the normal upload speed. I did not come to the conclusion on one single test.
But you installing a SSL certificate on your webserver doesn’t have anything to do with the tests of speedtest-cli. SpeedTest doesn’t USE your webserver when testing upload speed.
