HITs/sec and Transaction/sec

 HITs/sec and Transaction/sec

A Transaction is a group of Requests which creates multiple HITs on the server.

Hence we will see multiple HITs against one Transaction.

HITs/sec Graph helps to identify the Request rate sent by the testing tool.

High Response Time may cause less HITs/Sec

Eg :  Alogin operation which involves 10 HTTP Requests can be group together into a single transaction.

.".  When you see one dot in Transaction/sec graph there will be a 10 dots in HITs/sec Graph.

the hits per second is always per second where as throughput in per minute and sometimes in per second

In case of throughput; the higher or the better. This means that your server is capable of successfully executing that many number of requests per unit of time.

In case of throughput; the Lower the difference between throughput and hits per second (in same unit of time) the better for your system. If the difference is high that means that your server is not performing well enough.

In short hits per second is the total load on system and throughput is part of that load going successfully and the difference is the failed requests.
