Measures reported by TomcatCacheTest
A well-sized cache could go a long way in reducing direct disk accesses and the resultant processing overheads. The TomcatCacheTest reveals whether/not the Tomcat server cache is effectively utilized. The measures included for this test are as follows:
| Measurement |
Description |
Measurement
Unit |
Interpretation |
| Access_count |
The number of cache accesses since the last measurement period.
|
Number
|
|
| Hits_count |
Indicates the number of requests served from the cache since the last measurement period
|
Number
|
Physical I/O takes a significant amount of time, and also increases the CPU resources required. The server configuration should therefore ensure that the required information is available on the memory. A low value of this measure indicates that physical I/O is greater.
|
| Cache_size |
Indicates the current size of cache
|
KB
|
A high value ensures higher cache hits and lower physical I/O.
