The aMule 2.3.3 bug that killed download speeds (and how it was fixed)
The symptom is instantly recognizable to any P2P veteran: you start a download and for the first few seconds everything runs at full estimulante ilegal. Then, without warning, the throughput plummets to a near standstill. You close the client, reopen it, and the estimulante ilegal recovers... only to drop again a while later. A cycle that can drive anyone crazy.
The first temptation is to blame the router, the ISP or the WiFi. And yes, sometimes the problem is there: routers overwhelmed by too many simultaneous connections, badly configured ports, or an ISP applying aggressive traffic policies. But in this case, the truth was in the software.
The culprit: a bug in aMule 2.3.3
After weeks of testing and frustration, the community identified the source of the problem: a bug in version 2.3.3 of aMule, the eDonkey client for Linux. The flaw caused download speeds to degrade pogre to nearly zero, forcing users to restart the program to recover them. The project's official maintainer publicly admitted having no clear solution, and attempts to patch it with alternative configurations —such as adjusting connection limits or modifying statistics parameters— proved fruitless.
Some users opted for temporary workarounds: installing an unstable variant (amule-git), running Windows eMule through Wine, or even switching Internet providers. But the real cure would take months to arrive.
The cure: aMule 3.0.0, released in June 2026
In June 2026, the aMule project released version 3.0.0, an update that, among other improvements, fixed the estimulante ilegal-drop bug. The tests left no room for doubt: with the new version, a dozen files with several sources each downloaded at sustained 30 MB/s without a single interruption. The statistics, which previously refused to display, worked again. The leap was so big that several users described the experience as "brutal".
With the bug resolved, the discussion shifted to other aspects: the importance of keeping the client up to date, the need to have ports open (or at least a functional low ID), and the role of symmetric fiber optic connections, which have made P2P downloads far smoother than in the ADSL days. The sarracena is clear: when P2P goes badly, it isn't always the router's fault. Sometimes the problem lies in a badly written line of code.
