zabbix 6.0 运行一段时间就比较慢，数据库方面怎么处理比较好？

1.zabbix部分历史数据表，在创建的时候可以采用分区表的方式
诸如一下为oracle部分表:

-- Create table
create table ZABBIX.HISTORY_TEXT
(
  itemid NUMBER(20) not null,
  clock  NUMBER(10) default '0' not null,
  value  NCLOB default '',
  ns     NUMBER(10) default '0' not null,
  upd_time  TIMESTAMP(6) default SYSTIMESTAMP not null,
  ins_time  as ("ZABBIX"."UNIX_TO_ORACLE"("CLOCK"))
) tablespace ZABBIX_SCHE_DATA_TBS
 partition by range(UPD_TIME) interval (numtoyminterval(1,'month'))
(partition P_20230301 values less than (TIMESTAMP' 2023-03-01 00:00:00')
);

alter table ZABBIX.HISTORY_TEXT add CONSTRAINT PK_HISTORY_TEXT primary key (ITEMID, CLOCK, NS, UPD_TIME) using index local tablespace ZABBIX_SCHE_DATA_TBS;


create table ZABBIX.HISTORY_LOG
(
  itemid     NUMBER(20) not null,
  clock      NUMBER(10) default '0' not null,
  timestamp  NUMBER(10) default '0' not null,
  source     NVARCHAR2(64) default '',
  severity   NUMBER(10) default '0' not null,
  value      NCLOB default '',
  logeventid NUMBER(10) default '0' not null,
  ns         NUMBER(10) default '0' not null,
  upd_time  TIMESTAMP(6) default SYSTIMESTAMP not null,
  ins_time  as ("ZABBIX"."UNIX_TO_ORACLE"("CLOCK"))
) tablespace ZABBIX_SCHE_DATA_TBS
 partition by range(UPD_TIME) interval (numtoyminterval(1,'month'))
(partition P_20230301 values less than (TIMESTAMP' 2023-03-01 00:00:00')
);

alter table ZABBIX.HISTORY_LOG add CONSTRAINT PK_HISTORY_LOG primary key (ITEMID, CLOCK, NS, UPD_TIME) using index local tablespace ZABBIX_SCHE_DATA_TBS;

create table ZABBIX.HISTORY_STR
(
  itemid NUMBER(20) not null,
  clock  NUMBER(10) default '0' not null,
  value  NVARCHAR2(255) default '',
  ns     NUMBER(10) default '0' not null,
  upd_time  TIMESTAMP(6) default SYSTIMESTAMP not null,
  ins_time  as ("ZABBIX"."UNIX_TO_ORACLE"("CLOCK"))
) tablespace ZABBIX_SCHE_DATA_TBS
 partition by range(UPD_TIME) interval (numtoyminterval(1,'month'))
(partition P_20230301 values less than (TIMESTAMP' 2023-03-01 00:00:00')
);

alter table ZABBIX.HISTORY_STR add CONSTRAINT PK_HISTORY_STR primary key (ITEMID, CLOCK, NS, UPD_TIME) using index local tablespace ZABBIX_SCHE_DATA_TBS;

Mysql和oracle都可以，按照时间，定期删除分区数据，更新统计信息。
