....the partial write optimization in a more realistic benchmark setting. In addition to the PostMark benchmark, we also investigate the traffic savings on a debit credit benchmark [28] a TPC B like benchmark that is intended to model the workload on a database server that manages bank transactions [43]. Measurements reveal that the partial write script reduces bandwidth considerably for both the PostMark and debit credit benchmarks. For PostMark, total message traffic (in bytes) is reduced by roughly 54 . For the debit credit benchmark, the savings are more dramatic, as a full 96 of the ....

....of Computer Science and Engineering, University of Washington, Seattle, tom cs.washington.edu. The performance of small synchronous disk writes impacts the performance of important applications such as recoverable virtual memory [27] persistent object stores [2, 18] and database applications [33, 34]. These systems have become more complex in order to deal with the increasing relative cost of small writes [19] Similarly, most existing file systems are carefully structured to avoid small synchronous disk writes. UFS by default delays data writes to disk. It is also possible to delay metadata ....

....so on) Figure 1 shows the measured process to process bandwidths for 4 to 32 byte packets. 2.4 Benchmarks We use the Debit Credit and Order Entry benchmarks provided with Vista [5] These benchmarks are variants of the widely used TPC B and TPC C benchmarks. TPC B models banking transactions [10]. The database consists of a number of branches, tellers, and accounts. Each transaction updates the balance in a random account and the balances in the corresponding branch and teller. Each transaction also appends a history record to an audit trail. The Debit Credit benchmark differs from TPC B ....

....thread or a log processing thread will only process a single tuple or log record, respectively, each time it is scheduled for the CPU. The CPU cost parameters used to model query execution are presented in Table 2. 4.1. 3 Application Model The application model is based on the TPC B specification [17], modeling a bank with branches, tellers, and accounts and reflecting the history of recent transactions. Each transaction contains three updates, one for each of the Account, Teller, and Branch relations, and one insert in the History relation. In the experiments, the database size is fixed (1 ....

....file systems in realistic conditions. In laboratory settings, realistic conditions are usually simulated by the use of benchmark programs. A variety of benchmarks have been developed that are useful for predicting the performance of certain types of workloads. Some benchmarks, such as TPC B [21] simulate specific application workloads. Other benchmarks, such as LADDIS [24] measure particular file system characteristics that are of interest in a wide range of applications. LADDIS is designed to measure responsiveness and scalability in NFS file system environments. The suite of ....

These traces were captured using the instrumentation described above and are described more thoroughly in [Ganger93a] Several traces, named TPCB#, were cap 107 tured on a workstation executing the TPC B benchmark [TPCB90]. Other traces, named MultiWisc#, were captured on an 8 processor database server executing a multiuser database benchmark based on the Wisconsin benchmark [Gray91] Several traces from each workload configuration are kept because each trace is very short (6 50 minutes) A.2.2 System Level ....

.... are to larger files (mean size 96 kilobyte) The large files are usually read (60 of the time) and occasionally extended, written or truncated (15 writes, 15 extends, 5 deletes and 5 truncates) The transaction processing workload is based loosely on the TP 1 [ANON85] and TPC B benchmarks [TPCB90]. It is characterized by eight large files (210 megabytes each) representing data files or relations, five small application logs (5 megabytes each) and one transaction log (10 megabytes) The relations are read and written randomly (60 reads, 30 writes) and infrequently extended and truncated ....

....non transaction applications. The sequential read test measures the impact of LFS write optimized policy on the sequential read performance. 5.3.1. Transaction Performance To evaluate transaction performance, a modified version of the industry standard TPC B transaction processing benchmark [TPCB90] was used. The TPC B benchmark simulates a withdrawal performed by a hypothetical teller at a hypothetical bank. The database consists of relations (files) for accounts, branches, tellers, and history. For each transaction, the account, teller, and branch balances must be updated to reflect the ....

....can affect cleaning cost. The benchmark configuration is identical to that described in Section 3, except that the file systems are configured with a four kilobyte block size to match the block size of the database indexing structures. The TPC B benchmark simulates a checkcashing application [13]. The four files in the benchmark are described in Table 3. For each transaction, an account record is read randomly, its balance is updated, the balances in the associated teller and branch records are updated, and a history File Size Description account 237 MB 1,000,000 100 byte records branch ....
