2/14/2024 0 Comments Postgresql vs sql server 2014UPDATE: Thanks to complaints like this, Microsoft has raised the Standard Edition limit to 128GB! SQL Server 2014 New Features that Aren’t In Standard Edition Seriously? Standard Edition licensing costs about $2,000 per CPU core, but it can only access 64GB of memory? That’s ridiculous. We get less CPU power, less memory, and few (if any) new features.Īccording to Microsoft, if you want to use more than $500 worth of memory in your server, you have to step up to Enterprise Edition. So, installing SQL Server and PostgreSQL in the same server, when there’s some workload, the PostgreSQL have important performance degradation.Every release lately, Microsoft has been turning the screws on Standard Edition users. 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.
