iOS HTTPS transaction time ~2.5x slower than HTTP

[ScottDodsonDev]

On iOS, HTTPS is approximately 2.5x slower than HTTP. On Android, HTTP and HTTPS transaction times are about the same. iOS and Android HTTP transaction times are also comparable.

Server trust mode is set to nocheck. Requests are sent to a local server. Expect latency below 100ms but averaging 230ms when using HTTPS on iOS.

Is this a bug? This question is related to #25 ; however, Android is unaffected. Is there a way to improve HTTPS transaction time on iOS?

System info

• HTTP plugin version: 3.2.2
• platform and version: tested iOS 12.5.5 and iOS 15.0.2
• devices: tested iPhone 6 and iPad Air (4th generation)
• cordova version: 8.1.2
• cordova platform version: iOS 5.1.1

Hi @ScottDodsonDev, I agree 230ms latency sounds too much. How did you measure those values? Is it the time for the complete roundtrip or is it the diff between HTTP and HTTPS with exactly same setup? (e.g. same request endpoint, same request & response data, same sample size, etc.)

Oh and thank you for sponsoring me :)

Hi @silkimen! Complete roundtrip with exactly the same setup. I left a comment on issue #115:

This was fixed in a8e3637f2728809377286aa00d85321f291d2f19 but reverted in 4b964e8b7c92b106c7c225197e8c3980f6d1f231.

As with @chrisjdev, what worked for me was reapplying the same fix for #115, but I had to remove the fix for #399.

[silkimen]

Are you experiencing the problems mentioned in #197 after reapplying #115 and removing #399?

[ScottDodsonDev]

I haven't experienced any issues; however, I don't use downloadFile().

Thanks for your feedback! 👍

I'll test this combination on my side on a device. If I don't encounter any issues I think this should be a viable fix approach!
