Load trace
load.trace.scope=sides=client__phases=dec1

The load table shows offered and measured load from client side point of view. Offered load statistics are based on the request stream. Measured load statistics are based on reply messages. The 'count' column depicts the number of requests or responses.

The 'volume' column is a little bit more tricky to interpret. Offered volume is reply bandwidth that would have been required to support offered load. This volume is computed as request rate multiplied by measured mean response size. Measured volume is the actual or measured reply bandwidth.




2. Hit Ratios

Hit Ratios DHR
(%)
BHR
(%)
offered 60.81 43.94
measured 55.33 38.95

The hit ratios table shows offered and measured hit ratios from client side point of view. Polygraph counts every repeated request to a cachable object as an offered hit. Measured (cache) hits are detected using Polygraph-specific headers. All hits are counted for 'basic' transactions only (simple HTTP GET requests with '200 OK' responses).

DHR, Document Hit Ratio, is the ratio of the total number of hits to the number of all basic transactions (hits and misses). BHR, Byte Hit Ratio, is the ratio of the total volume (a sum of response sizes) of hits to the total volume of all basic transactions.

A better way to measure hit ratio is to compare client- and server-side traffic. A hit ratio table based on such a comparison is available elsewhere.

The 'Stream' table provides count and volume statistics for many classes of transactions. The 'Contribution' columns show count- and volume-based portions of all transactions. The 'Rates' columns show throughput and bandwidth measurements. The 'Totals' columns contain the total number of transactions and the total volume (a sum of individual response sizes) for each stream.

Note that some streams are a combination of other streams. For example, the 'all ims' stream contains transactions with If-Modified-Since requests that resulted in either '200 OK' (the 'ims/304' stream) or '304 Not Modified' (the 'ims/304' stream) responses.

Many combination streams, such as 'all content types' or 'hits and misses' stream, contribute less than 100% because properties like content type or hit status are distinguished for 'basic' transactions only. A basic transactions is a simple HTTP GET request resulted in a '200 OK' response. Various special transactions such as IMS or aborts do not belong to the 'basic' category.

The 'Object' table contains corresponding response time and size statistics for streams.

The 'Object' table provides response time and response size statistics for many classes of transactions.

Note that some classes are a combination of other classes. For example, the 'all ims' class contains transactions with If-Modified-Since requests that resulted in either '200 OK' (the 'ims/304' classe) or '304 Not Modified' (the 'ims/304' classe) responses.

Some statistics may not be available because either no objects of the corresponding class were seen during the test or no facilities to collect the stats exist for the class. The former can be verified using a 'Stream' table.
