CWP7 loads every page of the panel very slow. Email SSL

Hi everyone, I'm testing Centos 7 with CWP for my VPS. So far what I've seen I like.
I only have 2 problems, the CWP7 loads every page of the panel very slow, it takes eternities even with the Fast login activated, if at the end I decide for Centos 7 and its CWP, I am terrified of the hours that I will take to configure each site that I want to move from the shared server that I have now.
The server has these characteristics:
CPU Model: Intel (R) Xeon (R) CPU E5-2630 v4 @ 2.20GHz
CPU Details: 4 Core (2200 MHz)
Memory RAM (with Cache): 1.31GB / 8GB (16.4%)
Memory RAM (NO Cache): 1.06GB / 8GB (13.3%)
Distro Name: CentOS Linux release 7.6.1810 (Core)
Kernel Version: 3.10.0-957.1.3.el7.x86_64
Platform: x86_64 [kvm]
CWP version: 0.9.8.762
I was playing with the file /usr/local/cwpsrv/conf/cwpsrv.conf and increase the values ​​of worker_processes, worker_connections and client_max_body_size, but it still takes a lot of each page to load.
Is there any configuration that can be modified so that the CWP responds faster on your web page?
The other problem that I am presenting is with the email server and ssl, the ssl does not work or does not take it correctly, and the messages always end up in the folder Spam in gmail.
I am still reviewing the wiki and the forum to see what I have done wrong, but if anyone has any advice they will be grateful.
Thanks forum!

if cwp loads slowly then probably that server is slow....depends on your server provider it can be that some cheap servers are oversold and resource on them are a very low..mostly common issue is a slow disk.

Thanks, it works much faster, maybe it was some configuration or installation routine in the background that consumed resources.
