GlassFish Download Stats - Jan 2009 Update

This note provides a summary of the GlassFish download statistics from July 2005 until January 2009. Previous entries are dated March 6th, 2008, September 7th, 2008 and October 8th, 2008. The data point for "Tools" for Jan 09 is missing; I'll provide an update when that data is available.

Introduction

This entry complements other GlassFish adoption indicators; I tag relevant entries in TheAquarium as adoption. All indicators have limitations but my usual comment is that if all the indicators are pointing the same direction, they are probably right.

Some Caveats:

• The SDK d/l numbers are based on completed downloads.
• The Tools d/l numbers used to be completed but in the last couple of months changed to attempted.
• Counted downloads are from Sun.Com, Java.Net and NetBeans.ORG.
• We do not count downloads from our Maven Repository.
• We do not count Ubuntu, Solaris or OpenSolaris distributions.
• Some months I've counted a small (around 4K) number of d/ls from Solaris Express; I need to do a normalization pass.
• GlassFish is freely redistributable and we don't track other distributions.

Overall, I believe these are solid numbers, but if we discover a problem I will correct it and let you know.

Corrections and General Comments

Known Issues - I have not included the NetBeans numbers for January 2009 because we need to update our scripts to account for a change in the way NetBeans uses mirrors. I'll provide an updated chart as soon as the data is available. Note that the "Tools" data from Nov '08 and Dec '08 may also change.

Additional Comments - Downloads usually drop during the holiday season (late Dec/early Jan); this year is a bit unusual in that, although the worldwide financial situation seems to have encouraged more people to take a break between Christmas and New Year, overall, the d/ls didn't really drop.

New Charts

Next there are 3 data sets, collected into 5 charts with commentaries. The charts show monthly downloads starting in July 2005, right after we launched the GlassFish project, and going through last month, January 2009. The Y axis is normalized to 900K per month to simplify comparisons. The images link to a larger image for further inspection.

GlassFish AppServer in SDKs

This chart shows downloads of the GlassFish Server either by itself (Sun Java System Application Server, Sun GlassFish Enterprise Server and GlassFish Server) or in bundles like the Java EE SDK and the Java Application Platform SDK.

The peak around May '06 (223,079) was the release of Java EE 5 and GFv1 at J1 '06. Other local peaks correspond to GFv1U1, J1'07, GFv2, GFv2U1 and GFv2U2.

D/l numbers for Jan '09 were 178,494.

GlassFish AppServer in Tools

GlassFish is included in, and is the default container for, the most popular bundles of NetBeans 6.1, NB 6.0.1, NB 6.1 and NB 6.5 - I only count those from bundles including GF.

NetBeans 6.x has been very popular. The GlassFish portion of these d/l numbers for Apr '08 was 695,550. The corresponding number for Dec '08 was 531,019 - the Jan '09 numbers are not yet available.

GlassFish AppServer - Combined

This table just adds the previous two. The combined number for Apr '08 was 882,489 and for Dec '08, 706,868 - the Jan '09 number is awaiting the NetBeans number.

JBoss AppServer - From SourceForge

Finally, as a reference point, from SourceForge, d/l stats for All JBoss AS.

JBoss 5.0 was released in Dec '08; the total for all versions in that month was 126,989; 61,266 of them were JBoss 5.0 GA. D/ls of all versions in Jan '09 were 83,926; 41,564 of them were 5.0 GA.

Combined Chart

This one just collects the last two charts together.
