Re: [firebird-support] Firebird 3.0 performance, Windows 10 vs Mint, big different
Hello, I have tried to enable LargeSystemCache on Windows 10, no effect. With or without LargeSystemCache, the second query run on Windows 10 was about 33% faster than the first run, I guest File Cached did work although still saw disk activity. But even the second query runs, it was still about 20% slower than Linux Mint. I will avoid Windows and use Linux for firebird if it is possible. Regards, Anto.

Hello, Don't know, if this means file cached work or not. It works. I recommend to do several experiments with different Pafe buffers and FileSystemCacheThreshold values (Buffers > FileSystemCacheThreshold , Buffers < FileSystemCacheThreshold ), and check RAMMap. Try to do it with and without restart of the computer. If file cached worked, then there is something else that make Firebird runs slower on Windows 10. Windows 10 is a desktop OS, and it demonstrates slowness in so many cases, caused by so many reasons, so I would not use it as a server, until there is no other choice. I personally experienced slowness on one of my own desktops, and perfect performance on the another one. Better just stay out from this lottery. Try to make experiments with Windows Server, it will make more sense. Regards, Alexey Kovyazin IBSurgeon Anto

Thanks for your info. Downloaded ver 1.52, now it worked. On Process tab of RAMMap, firebird.exe took 2,183,484K. On File details tab, database file took 2,603,168K. Don't know, if this means file cached work or not. If file cached worked, then there is something else that make Firebird runs slower on Windows 10. Anto

Thanks for the info. I downloaded ver 1.52, now it works. As I expected, on Windows 10, File System Cached doesn't work.

RAMMap 1.51 works fine with Windows 10.
