Please provide me the suggestion regarding magento 2 store speed up?
I already set the minified js and css from the admin panel.
Also find too many request in the browser, how can we reduce server request in magento 2.
Please explain how magento 2 caching work?

realpath_cache_size=1M (careful, this is per apache process) realpath_cache_ttl=86400 (ok for production site)
Enterprise only tip:
(because it doesn't actually speed up the frontend but only the backend):
I do realize that you probably can't use all of the above tips but it's not about using them all, and sometimes you just make the choice to give a functionality a priority over performance and that's OK. If you can only apply some of them you will still increase speed and gain in user experience. And remember: because speed depends on many variables, some of the tips might not have an impact on your website at all while others can have a huge impact. So always test the impact of every step you take and take actions accordingly.
1.4 to 1.9 is a big jump, you are probably simply going out of computational resource and you need a better hosting.
If you want to make more tests on disabling extensions just make sure you are turning them off by modifying the xml files in app/etc/modules. JUst open the extension you wish to disable and set <active> tag to false. Manually flush the cache at each step by removing the content of var/cache directory (do NOT remove the cache folder itself).
If you get errors after disabling a module just turn it back on to fix.
Disabling from backend only disables their output, but they remain active.
Also check your cache engine, using Redis may result a in good performance boost.
For frontend you can use MSP LTS2 Full-Page Cache module: https://github.com/magespecialist/lts2
If you already did this, please make a better profiling with AOE_Profiler: https://github.com/AOEpeople/Aoe_Profiler

Firstly you if want good magento pagespeed, the store must be set to production mode using following command;
Now, for caching you can use magento's default full page cache, which does work as expected for most cases but go with third-party solutions like Redis or Varnish for more performance.
Installing and configuring these third party caches correctly is a long process so not including it here. Redis is relatively simpler to configure. You can follow this tutorial to install redis - https://www.tutorialspoint.com/articles/how-to-configure-and-install-redis-on-ubuntu-linux and to configure it you can use this explanation - https://magehit.com/blog/magento-2-varnish-and-redis-configuration/
You can reduce the number of server requests drastically by bundling js files in admin or by db.
