dtSearch Web system requirements and performance?
Supported: Windows 10, Windows Server 2016, Windows Server 2012, Windows Server 2008, Windows Server 2003, Windows 8.1, Windows 8, Windows 7, Windows Vista, Windows XP Service Pack 3.
In Windows 8, 8.1, and10 dtSearch runs as a desktop application only (it does not run in the "Metro" user interface). Windows RT is not supported.
Both 32-bit x86 and 64-bit versions of Windows are supported. (Under 64-bit versions of Windows, the 64-bit executables are installed in the dtSearch bin64 folder.)
dtSearch Desktop also requires that Internet Explorer is installed. Internet Explorer does not have to be your default browser (you can still use Netscape, Opera, or any other browser). dtSearch just needs certain components that are only available if Internet Explorer is installed on the computer.
dtSearch Desktop is designed for systems with a screen resolution of 1024x768 or higher.
Installation takes about 130 megabytes of hard disk space, depending on the options selected.
Additionally, you should have enough free space on the hard disk to build indexes of your documents. A dtSearch index takes about 1/3 the size of the original documents. Please see the article on Index Size for more information.
Recommended memory size is 8 Gb or more. dtSearch itself requires about 10-20 Mb of memory to search. Indexing can be done with as little as 30 Mb but more memory will result in faster performance.
1. Do not put dtSearch indexes on a compressed drive or folder. For example, do not use NTFS compression or encryption on dtSearch indexes. dtSearch indexes are internally compressed, so you will not reduce their size much, and operating system file compression can slow index access considerably. (dtSearch performance is not affected much if the documents are stored in a compressed drive or folder. It is only the indexes that should not be compressed.)
2. For best performance, use a defragmentation utility to keep your hard disk defragmented, and keep the hard disk at least 25% empty so the defragmentation utility can run efficiently.
3. Index updates will be faster and more reliable if dtSearch Desktop runs on the machine where the index is stored. It matters much less where the documents are located, because dtSearch just needs to read each document once to index it.
