如何通过改进MySQL的my.ini设置来减少磁盘负载

我创建了一个时间追踪应用程序，它可以捕捉400人每分钟的活动

这意味着，如果没有人查询我的数据库，我仍然每分钟有400个对MySQL的插入请求

到目前为止一切正常，但我必须给用户一个仪表板，让他们可以看到他们跟踪时间的每个条目

现在我有400人在查询我的数据库，启动查询页面后，系统变得非常慢，磁盘使用率达到100%的时间。我计划在服务器上部署更多应用程序，但在前进之前，我想解决这个问题

*** 下面是我在my-innodb-heavy-4G.ini的帮助下修改的my.ini文件。我的电脑运行MySQL 10.1.36-MariaDB，64位，3.60GHz，i7，8GB内存

我只是想知道下面的设置是否正确。我不希望我的服务器崩溃并停止工作。请帮助我添加或删除任何可能导致问题的设置行

However, in case you choose this method, then #    start replication for the first time (even unsuccessfully, for example #    if you mistyped the password in master-password and the slave fails to #    connect), the slave will create a master.info file, and any later #    change in this file to the variables' values below will be ignored and #    overridden by the content of the master.info file, unless you shutdown #    the slave server, delete master.info and restart the slaver server. #    For that reason, you may want to leave the lines below untouched #    (commented) and instead use CHANGE MASTER TO (see above) # # required unique id between 2 and 2^32 - 1 # (and different from the master) # defaults to 2 if master-host is set # but will not function as a slave if omitted #server-id       = 2 # # The replication master for this slave - required #master-host     =   <hostname> # # The username the slave will use for authentication when connecting # to the master - required #master-user     =   <username> # # The password the slave will authenticate with when connecting to # the master - required #master-password =   <password> # # The port the master is listening on. # optional - defaults to 3306 #master-port     =  <port> # # binary logging - not required for slaves, but recommended #log-bin=mysql-bin # Point the following paths to different dedicated disks #tmpdir = "E:/xampp2/tmp" #log-update = /path-to-dedicated-directory/hostname # Uncomment the following if you are using BDB tables #bdb_cache_size = 40M #bdb_max_lock = 10000 # Comment the following if you are using InnoDB tables #skip-innodb innodb_data_home_dir = "E:/xampp2/mysql/data" innodb_data_file_path = ibdata1:10M:autoextend innodb_log_group_home_dir = "E:/xampp2/mysql/data" #innodb_log_arch_dir = "E:/xampp2/mysql/data" ## You can set .._buffer_pool_size up to 50 - 80 % ## of RAM but beware of setting memory usage too high innodb_buffer_pool_size = 2G innodb_additional_mem_pool_size = 200M ## Set .._log_file_size to 25 % of buffer pool size innodb_log_file_size = 256M innodb_log_buffer_size = 8M innodb_flush_log_at_trx_commit = 1 innodb_lock_wait_timeout = 120 innodb_write_io_threads = 8 innodb_read_io_threads = 8 innodb_thread_concurrency = 16 innodb_log_files_in_group = 3 innodb_max_dirty_pages_pct = 90 ## UTF 8 Settings #init-connect=\'SET NAMES utf8\' #collation_server=utf8_unicode_ci #character_set_server=utf8 #skip-character-set-client-handshake #character_sets-dir="E:/xampp2/mysql/share/charsets" [mysqldump] quick max_allowed_packet = 16M [mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates [myisamchk] key_buffer_size = 512M sort_buffer_size = 512M read_buffer = 8M write_buffer = 8M [mysqlhotcopy] interactive-timeout

补充资料要求。在pastebin.com上发布并共享链接。您的MySQL主机服务器的RAM大小文本结果为：B显示全局状态；至少24小时正常运行后，C显示全局变量；D显示完整的进程列表；E完整的MySQLTuner报告信息，如果可用，包括-htop或top或mytop（适用于大多数活动应用程序），ulimit-a（适用于linux/unix限制列表），iostat-xm 5 3（适用于按设备和核心/cpu计数划分的IOPS），用于服务器工作负载优化分析。听起来像是一个简单的索引问题。但是我们需要看到showcreatetable、查询和解释SELECT。。。。威尔逊的请求可能会发现其他问题需要解决。还有，这张桌子有多大？@YatendraRanawat因为大约9个月后，您在2019年4月3日没有发布任何请求，所以您不再需要任何帮助来回答您的问题。请指出你想让我们考虑的任何事情。
