Today developer Aldostools has released a new version of webMAN mod. Check out the changelog and the downlod link provided below.
This is a new *test build* webMAN MOD v1.43.20
This new build has improved speed loading PS3ISO through ps3netsvr running on PS3 and morefree memory thanks to the smaller stack sizes used in the threads.
Also I reverted the dynamic buffer size for FTP to use static buffers of 128KB...
the increased buffer size doesn't seem to affect the performance.
