Slow access caused by Sharepoint Cache

When the product is released to the public network, every time the customer accesses the page, it is slow. After finding the cause, it is found that the appfabric cache on the server has an error;

 

Appfabric cache service: Used as a cache in the memory to store data accessed by applications, thus improving application performance.

 

Our server architecture is: ad management machine, OWA Server machine, Multiple front-end SharePoint servers, and ADFs uniform verification machine. Therefore, no matter which environment the front-end accesses, it will be cross-server, cross-server data retrieval is very inefficient every time, so it is necessary to cache access.

 

The reason for slow page access is that when the SharePoint site requests data from other servers, the cache on the Sharepoint Server is blocked by the firewall, that is, the data obtained by the appfabric cache is blocked, in this case, you need to enable the firewall and configure outbound and inbound rules;

 

Firewall outbound and inbound:

Outbound: you access the internet.

Inbound: Internet access to you

You can create inbound and outbound rules to block or allow connections to specific programs or ports. You can use pre-configured rules or create custom rules, the "New Rule wizard" helps you step by step to create rules. You can apply rules to a group of programs, ports, or services, rules can also be applied to all programs or a specific program. It can block a software from making all connections, allow all connections, or only allow secure connections, encryption is required to protect the security of the data sent through the connection. You can configure the source IP address and destination IP address for inbound and outbound traffic, you can also configure the source TCP and UDP ports and the destination TCP and UPD ports.

 

For our Sharepoint, this is caused by outbound traffic, so we need to prepare outbound rules,

The configuration rules are as follows:

1. Select "outbound" or "inbound", and click "create rule" on the right;
2. In the dialog box that appears, select "Port" for the rule type option and then click Next;

3. In the protocol and port, select "TCP" for the rule to apply to TCP or UDP, select a specific local port, and enter "22233". This is the default port specified by appfabric, and then click Next;

4. Select allow connection in the operation, and then click Next;

5. Check all selected projects in the preparation file and then click Next:

6. Finally, enter the name and description that you think are available in the Name field, and click "finish;

7. The status after completion is as follows:
