v21.57

Platform detail (平台详情)

What steps will reproduce the bug?(重新问题的详细步骤)

create more than 10 terminal connections with new tab for each, then switch to different tabs, you will see the switching time nearly 3 seconds, this is beyond endurance
创建10个tab，每个tab对应一个ssh连接，然后在tab间进行切换，会发现切换时间需要将近3秒，这个切换速度无法忍受

What should have happened?(期望的结果)

改进切换terminal tab的速度，控制在1s以内

Would this happen in other terminal app(是否能够在其他同类软件重现这个问题)

There is no such problem in other terminal apps, such as tabby or Ásbrú Connection Manager
使用tabby或者Ásbrú Connection Manager没有出现这个问题

@zxdong262 It's a little quicker than before within 10 tabs with v1.22.1, but the switching time will increase to 3s when there are 15+ tabs.
Thank you very much for fixing this, a greater improvement is also looked forwarding to .

@zxdong262 I just try with 1.22.30, and it is also excellent one in switching tabs, but after it's running several hours, it will take about 30% cpu load.
