X11 is good but slow in starbucks

I am sitting in Starbucks with network speed 15Mbps and try to use X11 forward for Netbeans coding. XMing is very low screen resolution so I changed to x410. The text is super clear now but the bandwidth not enought, so a little bit lagging.

You can see xming font is not clear in my 4k monitor if compare to local vscode

Changed to X410 and font is clear now, but it need some network bandwidth, so lagging in Starbucks. To solve this, turn on DPI scale
