0907 - Summary/Objective
0908 -
090801 - Follow up work at ref SDS 1 line 63.  Got information from Morris and
090802 - from an article in MicroTimes, ref OF 3 line 11.
090803 -
090804 - Looks like Windows 95 cannot meet our requirements for SDS.
090805 -
090806 -

0910 -
0911 - Progress
0912 -
091201 - Called Morris.  He said he has been a beta test person for Win 95. He
091202 - has not decided whether to adopt it after the release expected in
091203 - August.
091204 -
091205 -
091206 - RAM for DOS Apps
091207 -
091208 - Morris said Windows 95 does not provide the additional 140K of RAM for
091209 - DOS applications that os2 does.
091210 -
091211 -
091212 - Review of MicroTimes article showed following.
091213 -
091214 - Desktop & Directory/File Management
091215 -
091216 - Win 95 Taks Bar is better than the os2 launchpad, ref OF 3 line 85 and
091217 - ref OF 3 line 94.  The os2 Launchpad can be enhanced by a Lotus
091218 - product, ref OF 3 line 20.
091219 -
091220 - We have not found any benefit to the launchpad, so this is not
091221 - important.
091222 -
091223 - Win 95's Task Bar provides collapsable bird's eye view of all programs
091224 - on the computer, ref OF 3 line 97.  This might be valuable depending
091225 - upon what it really means.
091226 -
091227 - We have never found a use for the Shredder hyped as an advance, ref OF
091228 - 3 line 71.
091229 -
091230 - Both Win 95 and os2 use the right mouse button for menu access.
091231 -
091232 - Win 95 has better DOS file management than os2, ref OF 3 line 105, but
091233 - os2 offers better object management, i.e., it manages files
091234 - transparently by letter the user simply move and drop objects which
091235 - represent files and directories, ref OF 3 line 114.
091236 -
091237 - Win 95 has good feature for beginners called "Shortcuts" that enables
091238 - users to create file associations, but the reviewer found it can crash
091239 - if the user moves any files or directories on the disk.  Os2 manages
091240 - file and program associations better.
091241 -
091242 -
091243 - Performance - 32-bit Advantages
091244 -
091245 - In our experience, SDS reports are faster than under DOS, in fact most
091246 - disk access operations seem to go faster than directly under DOS.  I
091247 - assume this represents use of caching by the os2 operating system
091248 - using available RAM.
091249 -
091250 - Compiling the SDS program also seems faster under os2.
091251 -
091252 - Most functions though seem the same in single task mode.  If more
091253 - than one application is loaded, things slow down, but less in
091254 - Windows.
091255 -
091256 - Reviewer found 32-bit applications run about the same in Win 95 and
091257 - os2 as their 16-bit counterparts, ref OF 3 line 160.  This supports
091258 - earlier analysis on os2, ref SDS 1 line 63.
091259 -
091260 -      [See follow up on 64 bit systems, ref SDS 2 line 234.]
091261 -
091262 -
091263 -
091264 - OS2 has Better Multitasking
091265 -
091266 - Multithreaded programs run better in both Win 95 and os2 but there are
091267 - no multithreaded programs available on the market yet, ref OF 3 line
091268 - 164.  Win 95 therefore does not preemptively manage existing Win 3.1
091269 - or DOS 16 bit applications.  It still simulates multitasking, ref OF 3
091270 - line 173.
091271 -
091272 - Os2 fully controls and threads all applications, and so theoretically
091273 - has superior multitasking relative to Win 95.
091274 -
091275 -
091276 - Memory Impacts Performance
091277 -
091278 - Programs run one at a time (i.e., not in multitasking mode), then 8 MB
091279 - under Win 3.1 and 16 MB under Win 95 run a little faster than using
091280 - os2 with 16 MB of RAM.
091281 -
091282 - People with limited hardware (e.g. 8 MB RAM), Windows 3.1 for
091283 - Workgroups is a better solution than either Win 95 or os2, ref OF 3
091284 - line 209
091285 -
091286 - If you wish to run several programs at once like having a
091287 - spreadsheet open and a wordprocessing app, and maybe the system
091288 - clock or open a DOS window, then Os2 works better, ref OF 3 line
091289 - 213.
091290 -
091291 - Crash Avoidance seems better in os2, ref OF 3 line 240, but this
091292 - requires more memory.  Minimum os2 installation should be 16 MB RAM.
091293 -
091294 -
091295 - Applications
091296 -
091297 - Win 95 and Os2 support multimedia, including movies, CDs.
091298 -
091299 - OS2 has a 32 bit Internet and World Wide Web program that are not
091300 - available in Win 95.  These programs are excellent, ref OF 3 line 297.
091301 -
091302 -
091303 - DOS Application Support
091304 -
091305 - OS2 has a huge advantage because it offers users 740K of free RAM,
091306 - whereas Win 95 gives users about 580K or so depending upon the
091307 - configuration.
091308 -
091309 - Win 95 provides a Settings menu to configure each DOS application
091310 - separately.  The Windows PIF feature is not included with Win 95.
091311 -
091312 -
091313 - Ease of Use
091314 -
091315 - Reviewer found Win 95 easier to install than os2, ref OF 3 line 349
091316 - and easier to work with because of intuitive access to most features
091317 - most users will need most of the time, ref OF 3 line 362.
