It’s also considered to be one of the most compatible systems with Windows services. It’s preferred by companies who are dealing with large traffic workloads on a regular basis. Unlike Postgresql vs MySQL, SQL Server is a commercial solution. We wouldn’t go that far, but it’s definitely a highly universal solution. Some developers go even as far as to claim that it’s the most advanced open-source database on the market. PostgreSQLĪ tried-and-proven relational database that is known for supporting a lot of data types, intuitive storage of schemaless data, and rich functionality. So, installing SQL Server and PostgreSQL in the same server, when there’s some workload, the PostgreSQL have important performance degradation.Read our comparison of MongoDB vs MySQL to make the right choice of a database solution. Here we’ve to notice that SQL Server is a native Windows application, while PostgreSQL is multi platform and probably this compatibility across multiple OS is paid with the efficiency in Windows. When working together, SQL Server is the winner, it only decreases 23% but PostgreSQL decreases 82% when they run together. Test PostgreSQL in Linux is beyond the scope of our analysis, but I’m sure that it would improve a lot. But still, I’m impressed to see that difference. When running alone, SQL Server is much better than PostgreSQL, but as I said before it is not our goal and it can be for a lot of reasons, for example better implementation of DVD store or better drivers. The numbers are the results of the benchmark. N_purchase_from_start= 206466 n_rollbacks_from_start= 4110 Results The benchmark result is at the end of the output file: To solve the runtime error in ds2pgsqldriver.exe I modify the source code: in file c:\ds2\pgsqlds2\ds2pgsqlfns.cs at line 209 I change this block:Ĭ:\ds2\pgsqlds2\ds2pgsqldriver.exe -target=127.0.0.1 -run_time=20 -db_size=10GB -n_threads=40 -ramp_rate=10 -pct_newcustomers=0 -warmup_time=0 -think_time=0 > c:\Temp\testresults.txt 2>&1Ĭ:\ds2\sqlserverds2\ds2sqlserverdriver.exe -target=localhost -run_time=20 -db_size=10GB -n_threads=40 -ramp_rate=10 -pct_newcustomers=0 -warmup_time=0 -think_time=0 > c:\Temp\testresults_sqlserver.txt 2>&1 Executing ds2pgsqldriver.exe I get a runtime error.The script for creating the database and importing the data is for Linux bash pgsqlds2_create_all.sh so I port it to Windows, pgsqlds2_create_all.bat.For PostgreSQL in Windows I haven’t found something similar so I do it on my own, finding this issues:.Microsoft Windows Server 2008R2 Standard SP1 64-bitsĪfter install the RDBM it’s time to install DVD Store:.RAID controller: LSI Adapter SAS2 2004 Spitfire with 2 SATA disks in RAID 1.PostgreSQL benchmark because we don’t want to go deep on how DVD store is build, DB drivers’ performance and so on. We want to see how they would behave when working together, compared to when they’re working alone. The benchmark can be run on several databases and SQL Server and PostgreSQL are among them. It’s a benchmark that simulates a DVD store with a simple OLTP database. We decide to use the DELL’s DVD store benchmark. We said that because we would experience problems with I/O and memory pressure, due to the high use of disk and memory that is typical on. Obviously, the server would run under Windows. We were asked: “Is it possible to run SQL Server and a PostgreSQL in the same server?” I only test their performance’s affectation when they run in the same server, that I would never do. Notice: This is not the typical performance’s comparative between SQL Server and PostgreSQL.
