The following actions are performed at the time of access, so it might take a long time, especially for the first-time access.
From the second access onwards, various initialization processes have already been completed and various caches are enabled, which improves performance.
・ Load a tag library
On the first access, the tag library is initialized.
From the second time onwards, the tag library after initialization is used, which improves performance.
・ Loading and initializing classes
After startup, the class that is used for the first time is initialized.
From the second time onwards, the initialized class instance is used, which improves performance.
・ Create a cache
Add information required for access (especially information stored in the database) to the cache.
If the necessary information does not exist in the cache, it will be added to the cache after being retrieved from the database, regardless of whether it is the initial access.
Access to the database increases immediately after startup because there is no cache.
From the second time onwards, the probability of referencing the cache is higher, which improves performance.
・ Pre-compile and compile JSP
The first JSP file to be used is precompiled and compiled.
From the second time onwards, the compiled JSP file is used, which improves performance.
