安装之后操作Gitlab网页端时候会有些卡顿，可以修改配置来改善性能：

提前说明：我的机器配置如下
两个40线程的处理器 160G内存

# //处理器 CPU(s):                  40   On-line CPU(s) list:   0-39 Vendor ID:               GenuineIntel   Model name:            Intel(R) Xeon(R) CPU E5-2630 v4 @ 2.20GHz     CPU family:          6     Model:               79     Thread(s) per core:  2     Core(s) per socket:  10     Socket(s):           2 # //内存条 Memory block size:         2G Total online memory:     160G 

调整配置

修改配置文件sudo vim /etc/gitlab/gitlab.rb

# 设置数据库缓存 postgresql['shared_buffers'] = "4GB" # 设置数据库并发数 postgresql['max_worker_processes'] = 1 # 设置puma 、nginx进程数 puma['worker_processes'] = 8 nginx['worker_processes'] = 2  # 设置sidekiq并发数 sidekiq['concurrency'] = 1 sidekiq['max_concurrency'] = 1 # 禁用监控 prometheus_monitoring['enable'] = false # 关闭一些监控和性能基准相关的功能 prometheus['enable'] = false #prometheus_monitoring['enable'] = false alertmanager['enable'] = false node_exporter['enable'] = false redis_exporter['enable'] = false postgres_exporter['enable'] = false pgbouncer_exporter['enable'] = false gitlab_exporter['enable'] = false grafana['enable'] = false sidekiq['metrics_enabled'] = false  # 设置gitlab_rails组件的内存消耗 gitlab_rails['env'] = {   'MALLOC_CONF' => 'dirty_decay_ms:250,muzzy_decay_ms:250' } 

最后重新加载配置：

sudo gitlab-ctl reconfigure   

重新访问Gitlab，加载很丝滑~
